How so? AFAIK, string literal syntax requires you to

Because it isn't possible to learn of all Perl (5 or 6) in one go. And
in general you learn rules before exceptions to rules.
Agreed.
In general in Perl the replacement part of a substitu

I wouldn't mind eval() to be off by default, so to have to put a "use

As a unary lazy prefix, you could even just say

Of course, then people will wonder why

I would personally hope that Perl isn't that clever, but treats all
bracketing delimiters the
S5 says:
There is no /e evaluation modifier on substitutions; instead use:
s/pattern/{ doit() }/
Instead of /ee say:
s/pattern/{ eval doit() }/
In my perl5 code, I would occasionally take advantage of the "pairs of
brackets" quoting mechanism to do something along the lines of:
