Indeed, raising an exception is very slow for us since we use C++
exceptions, but it's only used in exceptional cases, or in very
explicit use cases like returning from a block (the other return
statements don't use an exception). Also the new runtime in the
upcoming version of Mac OS X seems to be faster.
I'm not sure we are both on the same page yet.
In your examples:
1.times { p 42 }
after the "p 42" there is a return. Perhaps not a return statement
but a return. Also, there is no ensure and no way to put an ensure in
without a "begin / end" pair.
So, what I'm suggesting is to make:
begin
foo
return here
rescue
dog
end
be the special case. Not:
1.times { return 18 }
I'm guessing that is what you are doing but I wasn't sure.
