Re^4: regexp list return 5.6 vs 5.8

in thread regexp list return 5.6 vs 5.8

From what we've already discussed I would have expected the outcome:

the return list is constructed at compile time.
at runtime, the list (@x, @y) is evaluated in the caller's context, so it resolves to the comma operator, returning it's last argument - @y
then the array @y is evaluated in the caller's context, which happens to be scalar, hence 4 as a result.

Pretty much the same as

perl -le '@x=qw(a b c);@y=qw(a b c d); $f=(@x,@y); print $f'
4
