/me makes mental note to investigate B::Deparse sometime soon. Interestingly enough, and this is now way beyond useful.

$foo = 'hmmm';
bar  = 'why?';
print $foo.bar.me

Deparses as

$foo = 'grrr';
do bar = 'why?';
print $foo . 'bar' . 'me';
[download]

Of course they break in different ways. do bar = 'why?' dies with a compilation error. Can't modify do "file" in scalar assignment
bar = 'why?' Gets through with a warning, but when used with . results in a error : Undefined subroutine &main::bar.
My presumption is 'bar=' does something ugly to the symbol table - and why not? its pretty cruel use of syntax, sadly it's also an easy typo.

use strict #or die screaming.$!
