Except, don't use = as your separator. It breaks people's brains. Use
curly braces instead:
$full_path =~ s{//}{/}g;
or anything which doesn't already have a strong semantic map already
(which is hard, because this is Perl, and Perl uses almost all the
punctuation for something), and which can reasonably be assumed to be
obvious to a 6 months Perl user.
Curlies are great for pick-your-delimiter stuff:
q{single quoted}
qq{double quotes}
qx{quoted executable}
qr{precompiled regular expression}
m{match}
s{match}{replace}
If absolutely necessary (for example the string/expression contains
unmatched }s, I'll use ()s, []s, !s or at worst #s.
All the best,
J
