You could provide supporting evidence by examining every use of
switch in the dmd, phobos, and druntime source code, and see
what percentage of those would benefit from your proposal.
Consider, for example, the scope guard statement in D. It is
extremely useful - but it is an unusual form (doesn't exist in
other languages) and programmers just don't think in those
terms. Andrei & I constantly have to work at 'selling' the
benefits of it. It still hasn't really caught on.
The scope guard statement is my all-time favourite feature in D.
It's so much easier to reason about than several layers of
try/catch/finally.
A close second is the Contracts, especially as it can be applied
to interfaces. a huge win for service oriented programming.
