Neat hack!

Along the same lines, I have a set of DLMs here that add things like
foreach, map, filter, reduce, etc. to IDL along with lambda functions
and lists:

http://www.ittvis.com/info/hof/

For example, with the foreach DLM, your example becomes:

foreach, lambda('x: print, x', /P), myarray

There is also a pure IDL version for functions called 'each()' which
is quite useful.

Map, filter and reduce work pretty much as they do in Python (with
extensions). There are also compose, apply, cart, accumulate, and
group higher-order functions. With cart() it is possible to do the
equivalent of Python list comprehensions.

If you try it and have any questions let me know.
