AFAICT, release 2.074.0 has regressed move semantics in function
return statements.
As a consequence, my package
https://github.com/nordlow/gmp-d/
no longer compiles.
At master branch, `dub build` now errors as
Performing "debug" build using /usr/bin/dmd for x86_64.
gmp-d 0.0.1+commit.126.g660d82b: building configuration
"library"...
src/gmp/z.d(484,20): Error: struct gmp.z.MpZ is not copyable

src/gmp/z.d(921,16): Error: struct gmp.z.MpZ is not copyable
because it is annotated with @disable
/usr/bin/dmd failed with exit code 1.
which means that the return statement at
https://github.com/nordlow/gmp-d/blob/660d82b99abeef2b26ef3c9c4525d08a2aafdc55/src/gmp/z.d#L484
can no longer move the expression `y`.
I don't understand why this specific case fails when others in
the standard library apparently hasn't.
Help, please.
