Perhaps. But that will become very difficult indeed. Because in Raku, grammars are just a different way to write code. Grammars are really just specialized classes. And tokens / rules / regexes are just specialized methods. It

`INIT $ RAT-OVERFLOW = CX::Warn` will produce a warning whenever a switch to Num happens. `INIT $ RAT-OVERFLOW = Exception` will throw an exception whenever a switch to Num would happen. If you want to define your own behaviour, you can. F

And for 1.5 years now, you can have the FatRat behaviour by simply adding `INIT $*RAT-OVERFLOW = FatRat` to your program.

Newer versions of Rakudo allow you to tune this behaviour dynamically through the $*RAT-OVERFLOW dynamic variable (which defaults to Num for the described behaviour). See: https://docs.raku.org/language/variables#$*RAT-

FWIW, the JVM is one of the supported backends of the Raku Programming Language. Has been for quite some time actually. It was the first additional backend supported after Parrot, and provided a template for supporting the MoarVM and Java

Indeed. The original plan envisioned Perl being a slang in the Raku Programming Language. That plan failed because Perl is largely dependent on C-code plugins that are used whenever Perl is considered to be too slow (which is often). So

Saying that the Raku Programming Language is a flub, indicates to me that you do not know it at all. Getting Unicode support right by itself should be an indication that it is better than Python 3 in that respect. And let's not start

I think it's a credit to the hard work many people are doing on the Raku Programming Language.

Completely biased opinion: try Raku. It is easier to get into.

Note that the Raku Programming Language has pure ASCII equivalents for all operators as well, for the Unicode challenged. E.g. ≠ vs !=, ≤ vs <=, ≥ vs >= etc. etc.

subset OneToTen of Int where 1..10; Why make it more complicated? :-) The secret is that given values are smartmatched against the given object. And the values 1 through 10 will return True if smartmatched against the 1..10 Range object.

$_ is generally referred to as "the topic" in documentation and Raku parlance.

No. In the Raku Programming Language there are several non-ASCII operators, although each of them has a pure ASCII equivalent. Some examples: ≤ vs <=, ≠ vs !=, ∈ vs (elem), etc. The full list: https://docs.raku.org/langu

Actually, the limited precision is the default (caused by the numerator as well as the denominator having to fit in a 64-bit integer). By default, when it not longer fits, it will convert to floating point (called Num in Raku). But this be

The rule for kebab-case (regardless of whether or not it has a sigil) in Raku is: - each part of the identifier must start with an alpha character - cannot end with - So, "foo-bar" would be legal, "foo-" would not, &quot

by lizmat 4y ago
That works, but isn't necessary in Raku. As long as the right side of the hyphen does not start with an alphabetic character, you're good: my $a = 45; say $a-3; # 42
