I've been programming for (35-9=) 24 years myself,  and  I  find  the
best way to learn a new language is to *read* every example snippet I
can find, with a reference book close by. Eventually, the *rhythm* of
the language starts pounding in my head... and my fluency is close at
hand. That's how I learned Perl, and now I'm one of the drummers. :-)
