If you explicitly instantiate the templates foo and bar in the

if you change the declaration of foo or bam to "ref T x", ie..
auto foo(T)(ref T x)
auto bam(T)(ref T x)
then the compiler complains thus...

This was wrong. `enumerate` can infer. It's `lockstep` that
cannot.

The trouble seems to be when slicing the entire tuple. Even in

Hi d community,
I got a strange behavior since dmd 2.090 (dmd 2.089 is the last
working version).
See this reduced code: https://run.dlang.io/is/yoyHXC
I would expect that foo() returns 2.
My guess in foo is: The return value of val is saved locally as a
ref int and then the destructor of S
