"Mostly, that I will stick to qw(...) in the future."

Just be aware of this common mistake: 

$ perl -we 'print "$_\n" for qw{ a b c };'
a
b
c

$ perl -we 'for qw{ a b c } { print "$_\n"; }'
Missing $ on loop variable at -e line 1.

$ perl -we 'for (qw{ a b c }) { print "$_\n"; }'
a
b
c

You can leave the parentheses off when for is used as a statement modifier; but not when it introduces a compound statement. See perlsyn for more about that.

It's a common mistake because, although it was never really valid, Perl didn't report a problem until v5.14.0. For details, see:
