-------------------------------------------------------------------------
$ cat test.pl
sub MAIN(@args where sub { False }) {
say ":)"
}
$ perl6 test.pl
Usage:
test.pl <args>
$ cat test.pl # note the slurpy
sub MAIN(*@args where sub { False }) {
say ":)"
}
$ perl6 test.pl
Constraint type check failed for parameter '@args'
in sub MAIN at test.pl line 1
in block <unit> at test.pl line 1
--------------------------------------------------
I expect USAGE in both cases, since it's both exactly invalid use of MAIN.
Patch and spectest incoming.
