Gosh, I hope not.

I don't think this will DWYW, as fi

I don't know, but guess not.
Do (most of) the basic types morph themselves into Codes, when needed?
I don't consider it type morphing. If your examples parse
at all they will be dispatched as usual
say 4

say 42();# 42?
say "Perl"();

Hi,
# Way 1
my $MEANING_OF_LIFE is constant = 42;
# Way 2
my &MEANING_OF_LIVE = -> () { 42 };
# or
sub MEANING_OF_LIVE () { 42 }
# Then one can use sigilless constants:
say MEANING_OF_LIVE;
# Way 3 (still possible?)
use constant MEANING_OF_LIVE => 42;
# Way 4 (evil?)
