This is related. The original poster wanted a language extension. I
don't think we'll do this; a language extension would need a strong
justification, and this particular extension would mean mixing flow
control with semantic analysis, which would be pretty ugly to
implement.
The PR is about removing redundant casts from the generated code.
I'll upload my patch into the PR soon. It works ok, but as I recall
it needs VRP to remove everything. When I upload it I'll put the info
in the PR.
