Shifting left `int4 << int` is "ambiguous" ? #817

Closed rickbrew closed 1 month ago

rickbrew commented 1 month ago

IIRC this was something that couldn't be resolved in a previous version of C#, but now it's possible?

You can't do something like,

int4 x = ...;
int4 y = x << 1; // "ambiguous"

If you cast to int4 then it's fine of course

int4 x = ...;
int4 y = x << (int4)1;

Same thing happens if you use uint[4]:

There might be other shift scenarios that aren't working conveniently, I haven't looked just yet
