Quoting James B. firstname.lastname@example.org:
one of the languages that they use in academia to teach
programming is lisp. you might want to take a look at that too.
but just to learn because doing something real in lisp is
Is this true for people who learn Lisp as their first language?
They adapt to the pain – it’s mainly just syntactic. The thing
about Lisp is that the syntax isn’t very humane, but you can
certainly get used to it (macros are a powerful incentive to come
to grips with it once you discover their utility).
But that Lisp is actually “hard” is a myth, due mainly to the way in
which the language is usually taught. Syntax aside, the language is
plenty familiar. There’s nothing magical about it. It’s just that
most Lisp courses are taught on something of a “throw the kid in
the deep end of the lake and he’ll learn to swim real quick”
People get jittery about things like first-class functions because
they’re presented as so strange and mystical, but really they
aren’t. What are Ruby blocks, after all? They’re just syntactic
sugar for lambdas.
Ruby is a sly little victory for functional programming, actually.
I mean, what if you told someone that a language had no for loops,
and that instead you had to get by by passing functions to iterator
“How can I do anything useful without for loops?!” they would say.
That’s a common objection to Scheme, actually (never mind that
Scheme actually does have ‘do’, which is the same thing). At that
point many Scheme advocates start talking about recursion, and
people’s heads explode.
But then Ruby showed people it was okay.
We don’t normally use recursion, but then again neither does
well-written Scheme code for the most part. In functional
languages when you need recursion you usually want to reserve it
for implementing little combinators (of which ‘map’, ‘loop’ and
‘each’ are simple examples) and then build on top of those.
