My introduction to Perl was motivated by a performance issue. I had = been using a set of sh/awk/... scripts to generate the source files = (troff and file trees) for my Prime Time Freeware book/CD-ROM = collections. One of the cooler aspects of this approach was that I = could use sh as a macro processor, substituting assorted values into the = awk (etc) code. However, running the scripts was taking about three hours (!), so I = tended to start them up just before going to bed. This worked, for some = value of "work", but it was kind of a nuisance... So, upon the recommendation of Erik Fair, I transliterated my scripts = into Perl. The similarity of Perl syntax to my previous combination of = languages was so strong that the effort was almost mindless. And, even = though I made no attempt to use any Perlish features, the new scripts = ran about five (!) times faster. My assumption is that this was mostly = due to getting rid of the process startup times. My move to Ruby was motivated by the Perl 6 clusterfudge. After = watching Perl 5 sit at a siding for a few years, with no relief in = sight, I took another friend's advice and tried out Ruby. Aside from a = few odd differences, it was quite familiar and a very easy transition. = However, the syntax seemed much "cleaner" than Perl's (Matz has very = good taste, IMHO). So, it's still my choice for small, single-threaded = scripts. That said, if I want to write larger and/or concurrent apps, I turn to = Elixir. It gives me Ruby-like syntax (with nifty extensions such as = pipes), strong support for concurrency and distribution, macros, etc. -r
