Result: 8MB executable size (!).
Of course, this comes at a runtime cost of an added level of
indirection (now you have to call a virtual function through
the interface to integrate with earlier components in the
pipeline). But at a 60% reduction in executable size, I think
it's a worthwhile tradeoff. :-)
That's a very interesting idea!
However, I wouldn't want to insert this into code manually, maybe
a simple flag-opt-in support in DMD that detects UFCS pipes with
X components and then inserts the type erasure hack could solve
most problems for the time being? That way it wouldn't create a
WTF moment when explaining D code and when Stefan or someone else
manages to implement something more sophisticated, no code would
need an update.
