Can you point to any words in the standard that allows the lambda
expression to get "recompiled" for different calling conventions?
Since the lambda has no "auto" parameters, it is NOT a "generic" lambda
that gets recompiled under different usages, so I am not sure what basis
you have to claim the ability to "compile" it generically.
This might just be a common extension.
The fact that others have pointed out that when compiling for current
operating systems, the common compilers that understand those reserved
symbols point out that they are just ignored.
Did you actually look at the generated code to see that it in fact DID
get generated twice? or are you just guessing (perhaps wrongly) as you
seem to do so often.
