That's similar as in "it's an interpreted language for scientific 
data handling and prototyping" not similar as in "the syntax is 
just about the same" As a language it looks very C-like -- not for the
curly-bracket haters. 

Yorick is much smaller than IDL and doesn't have geographic maps and 
sundry other things. However it is free software and the array syntax is 
very sophisticated, the contraction operator being in some ways one of the 
better features as Craig points out. It seems fairly stable and behaves well
when you try to actually achieve something with it -- this isn't true
of some similar packages.
