Re^2: How to do regex backreferences within $variable replacement text?

re: Security, that's half of the reason why I would prefer not to use eval() at all (the other half is performance reasons, since eval() is recompiled each time its executed at runtime.)

Compilation time is going to be there no matter what solution you use; something needs to figure out which characters are plain and which are part of the name of a variable to embed, and something much actually do the embedding. True, not some compilers are faster than others, but I suspect that `perl` is very quick at compiling a string literal, especially since it's already loaded in memory.	[reply] [d/l]
