First, I have a solution. But it's ugly as sin, so I was curious if
there was a better one.
I want someone to call a function with two arguments, a regular
expression and the expression to change it into. So calling:
foo('.(b).', 'the middle letter was $1!')
would result in the string
"the middle letter was b!"
The solution is:
$a =~ s/$b/eval("\"$c\"")/e;
as can be seen in this test program:
#!/usr/bin/perl
$a = "abc";
$b = ".(b).";
$c = "the middle letter was \$1!";
$a =~ s/$b/eval("\"$c\"")/e;
print "$a\n";
Anyone have a better way?

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
