Correct me if I'm wrong, but it's my understanding that for loops in
IDL are so painfully slow because so much effort has been put into
making vector operations so mind-numbingly fast, and there's some
trade-off to be made there. I think the ranter has overlooked that
critical point. As someone who does a lot of image processing, I
rarely have occasion to operate on particular array elements anyway.
I'm still a relative newcomer to IDL, but my biggest gripe has (and
always will be) inefficient memory allocation... it's a pain when you
can't hold two large arrays (maybe 1/4 of available memory each) in
memory even though IDL has 2GB to play with. The rest is details and
idiosyncracies. Every language has its strengths and weaknesses, the
trick is to know what language is ideal for your task, or if you're
forced to use a particular language, learn to write code that exploits
the strengths of that language.
