At a variable or field of Collection or array type (or even method call with iteratable return type) provide "Iterate through..." intentions creating foreach, indexed or iterator loop

Sounds a bit like http://intellij.net/forums/thread.jspa?messageID=5190436

IMHO one-click intentions would be more convenient (and easily foundable)

I think you're right.

I assume, you're suggesting a _single_ intention, that tries to be as smart as possible (by looking at current reference)?

I mean there could be two or three intentions depending on the position:

foreach/indexed loop for arrays
foreach/iterator loop for collections
foreach/iterator/indexed loop for lists

For java.util.Map you might suggest

iterate map keys
iterate map entries

In addition java.util.Enumeration could be supported.

Some other ideas...

If expression on which intention is invoked is part of a statement, I assume iteration statement would be generated immediately following the current statement
However, it would also be convenient to simply compose some (collection-yielding) expression on a new line, and then invoke the intention from that. It this case iteration statement would really be generated "around" the expression (instead of: as next statement)
