Ask HN: Missing comma (Julia)

1 points by nyc111 8y ago

julia> +(2 3 4) ERROR: syntax: missing comma or ) in argument list If Julia knows that commas are missing, why can it compute the sum without commas?

It can't differentiate between whether a comma is missing or a paren. This isn't a runtime error so in order for the program to run it would have to generate all possible permutations of what you could have run with corrected syntax and then output values from the multiple programs. That's not really how programming languages are supposed to work.
