for(Max,Max,F) ->  F(Max);
for(I,N,F) -> F(I),for(I+1,Max,F).

for(1,10, fun(I) -> io:format("...." end)

The code is *shorter than the documentation"

writing the code is quicker than finding the documentation and reading it - this
is true in most programming languages which is why programmers write

This happens all the time I wanted hex2int after 20 seconds in google I gave up
and wrote it myself - this is also true for javascript C, ... as Wirth once said
It is better to know one langauge very well that to know many languages

Hint: read books and type in the examples. for/3 is in my book :-)
don't rely on the web for information - (example Douglas Crockford's
Good Parts of JavaScript - I learnt more in half an hour reading this
than dozens of
hours reading appallingly bad articles on the web)
