   in a strange way I both agree and disagree with this: + I use raku a lot so it is very natural to embed raku code in a Rak CLI - I think that there a several benefits of the Rak tool that vanilla grep (or ripgrep) does not offer (eg. embedd

   installing raku via rakubrew.org is quite painless tbh, it comes with zef, the standard raku package manager and then just ```zef install App::Rak```

   ok - but raku has a reinvention of Numeric that is less esoteric, and more practical ... what you mention is that an Int isa Rat isa Real isa Complex isa Numeric ... and thus in Scheme or Lisp, then the Number Tower class model is one of su

   and yet, raku is the first serious attempt to unify Int-Rat-Num-Complex types into a cooperative Numeric space --- which I think is a good design given its untyped default approach

   Nearly, the docs say "To prevent the numerator and denominator from becoming pathologically large, the denominator is limited to 64 bit storage." ( https://docs.raku.org/type/Rat ) Please bear in mind that in r

   I disagree that graceful degradation from Rat to Num (ie double) when Real numbers over- or under-flow is a misfeature. We could (and have) debate whether FatRat should be the default, but imo the right expectation for an untyped language s

    This post is focused on the lifecycle of the standard raku scalar variable with the $ sigil since it is the obvious inheritor of the perl $ variable which can also be seen in similar guise in places like Bash, PHP and SASS.

    I have greatly enjoyed raku for several years. Pros: can whip up a quick one-liner (raku -e instead of bash), then grow it to a CLI command (with no boilerplate to handle args, help), then refactor that to simple OO when it gets bigger (ins
