JavaScript support for s///e.
I wrote the below (cut) function for those who mourn JavaScript's lack of an
equivalent to Perl's s///e.

So, I have a few questions:
- Was this a good idea? Am I inappropriately trying to mold JavaScript in
Perl's image? (I'm rather new to the Tao of JavaScript, as it were.)
- Is this the right way to do it? I originally created a replaceEval function
that operated like String.replace except for applying eval() a specified
number of times (default 1), but I ended up scrapping that because the
eval()s would get invoked in the scope of replaceEval's definition rather
than in the scope of its invocation, preventing replacement-strings from
using local variables (including local functions). I'm not sure if this is
really the Right Way, though.
- How inefficient is this? Obviously it involves applying a bunch of eval()s
and String.replace()s, but I don't know exactly how intensive those are. Is
this something to be concerned about? Is there a way to improve it?
- Any other comments?
(BTW, if the above function looks useful to you, feel free to use it.)
