Hi,
This method is mine :) Ok, with a little IRC help from Radoslav Hodnicak.
Why #become: ? As Marcin already suggested is a problem how to nil all
existing elements in a collection, so to be garbage collected. This is
specially problematic when collection has many elements and just doing
an usual remove is too slow. In that case #become: is much faster, even
that this method is slow on some dialects. Also, collection identity is
preserved. But main point is that all elements are for sure GCed!
Best regards
Janko
