Several areas of the docs then need to correct that. No matter what you
decide, a user should be able to take the tricky words in an error message
and usefully find them in the docs.

[perl #131922] [LTA] "Variadic" or "slurpy"?

[Larry Wall via RT]

Only *@foo and *%foo are slurpy, as in "slurping up the rest of the arguments. 
But the term "variadic" refers to all optional arguments including named ones, 
so it would be incorrect to call those "slurpy", because they don't.  It's like 
the difference between * and ? in regex.

[perl #131922] [LTA] "Variadic" or "slurpy"?

[Aleks-Daniel Jakimenko-Aleksejev via RT]

This could've been a LHF, except for these tests:
https://github.com/perl6/roast/blob/4bfd6d2374cb4ea1b8fa057a5f294b988e4dec44/S32-exceptions/misc.t#L180-L185

¯\_(ツ)_/¯

But yes, I think it should say “slurpy” everywhere.

Consider this program which I don't expect to work (and it doesn't compile):

sub show-the-arguments ( *@args, $i ) {
put "The arguments are @args[]";
}

show-the-arguments( 1, 3, 7 );

The error message says "variadic":

Cannot put required parameter $i after variadic parameters

But another sort of error uses a different term:

sub show-the-arguments ( *@args, $i ) {
put "The arguments are @args[]";
}

This time the error messages say "slurpy":

Only one slurpy positional allowed

The docs almost almost always say "slurpy" and the uses of "variadic"
only appear as synonyms next to "slurpy":
