I'd rather go for extra semicolon:
- %set= map {; $_ => foo($_) } @list;
demo with perl -de0
DB<45> x map {a=>1} 1..3; # seeing hash, but co +mma missing syntax error at (eval 55)[c:/Strawberry/perl/lib/perl5db.pl:738] line +2, near "} 1" DB<46> x map {a=>1}, 1..3; # seeing hash again 0 HASH(0x2f501e8) 'a' => 1 1 HASH(0x2f4a1e8) 'a' => 1 2 HASH(0x2f4d0e0) 'a' => 1 DB<47> x map {;a=>1} 1..3; # seeing code 0 'a' 1 1 2 'a' 3 1 4 'a' 5 1 DB<48>
YMMV! :)
edit
Anyway, Perl should check for the missing comma. I suppose this happens too late for the parser.
