yeah, i'm aware that perl is used by biologists, but the question is more like, "should perl be used by biologists?" no question that c is not a great choice, but what about python? or, hell, javascript, even? for the kind of programs biologists would want to write (i.e. programs that need to describe a system that performs several tasks rather than programs that need to perform one or two specific tasks), it'd be helpful to have a language that not only has data structures like arrays/lists and hashes/dictionaries but also a data model that includes things like classes as a primitive. python in particular has numpy/scipy. perl's syntax for regexp matching definitely makes it a good choice for programs that have to do a lot of string-munging, but that's what i meant by "sys-admin-type stuff."

In Perl you can do what numpy/scipy do with PDL, the Perl Data Language. Perl is not just a string mangling language, it's a full-fledged generic programming language.

Classes are not primitives in either language... primitives contain a value instead of a reference. I think you mean that classes are first order, but I don't want to put words in your mouth so perhaps you can clarify what the difference you are pointing to. I think, given that Perl is being used, the question might be, what features make javascript or Python a good reason to switch? I'd want to avoid losing features. Perl is stable. Perl written two decades or more ago still runs fine in modern perl. That's important for data analysis, especially in the sciences. I'll have to read up on Python ... I'd want a tie equivalent to be able to treat large files as if they were arrays/hashs (lists/dicts) without loading them into memory as such.
