Like all conditionals, it depends on the program's context... and program's context is entirely dependent on the programmer. Good programmers don't use regexes for everything (especially "most conditionals") because it makes it 1. difficult for other programmers to sit through and figure out what the regex is trying to do 2. difficult to be precise, there could be many possible matches 3. impossible to separate implementation logic from business logic 4. (CPU-wise) expensive to do something that could have been better designed with alternate, non-english based approaches Regexes make for some shabby, unmaintainable code. Use regexes only when absolutely necessary. For most machine-machine communication, there are well defined data interchange formats than human language that needs "regex parsing" (data interchange/serialization formats such as YAML, JSON, XML, etc.,). For most human-machine communication, there are MVCs (like perl Catalyst) that let you separate business logic from the data representation and user interaction. You can still use regexes, but such frameworks minimize your urge (as perl "scripters") to use regexes and other bad practices. More than raw language skills, good practices make good programmers.
