[Insight-developers] itkSetMacro with STL types

[David Cole]

I'm fairly certain we avoid STL types in public set/get method
signatures for a handful of reasons.

The two that come immediately to mind are:
1) compilation speed (avoiding including the stl headers in other
headers is a good thing)
2) wrapping languages

Maybe both of these are, at this point, merely historical footnotes,
... but first, before solving "the problem", I'd see if I couldn't
rather avoid it in the first place.

Where do you need a vector or a set that's in the public API of ITK?
