Re: [Fred] Strange behavior of variable in substitution expression

The e flag enables evaluating the replacement string as a Perl expression. You can use both g and e in the same replacement: $foo =~ s/source/target/eg;
An alternative to the ternary operator or the successive else or case statements would be to use a hash to find the replacement string from the user input.
