Re^10: Definition of numerically equal and rationale for 'you' == 'me'

That works in Perl 5 as well:

perl -Mconstant=x,1 -MO=Deparse -e 'print x x x'
print '1' x '1';
-e syntax OK

But:

perl  -MO=Deparse -e 'sub x {1} print x x x'
sub x {
    1;
}
print x(x(x()));
-e syntax OK

Exactly. That's what I meant with my last paragraph in Re^7: Definition of numerically equal and rationale for 'you' == 'me'. Without sigils, you have to be much more careful, about whether a term or an infix is expected, and errors are more likely to go unnoticed. So possible, but in general a bad idea.
