how do you disambiguate function calls

also, can you disambiguate between these two:

fn __mul__(self, other: MY_SIMD[type,1]):
  // splat multiply
fn __mul__(self, other: MY_SIMD[type,simd_width]):
  // flat multiply
...

MY_SIMD[type,1]*MY_SIMD[type,1] // error: ambiguous call to '__mul__'

fn __mul__(self, other: MY_SIMD[type,1]):
  // splat multiply
fn __mul__(self, other: MY_SIMD[type,simd_width]):
  // flat multiply
...

MY_SIMD[type,1]*MY_SIMD[type,1] // error: ambiguous call to '__mul__'

i can call it splat_mul() instead

it works for builtin simd maybe uses one function? implicit cast splat from SIMD[type, 1] to SIMD[type,simd_width] MLIR stuff?

There’s no way for the compiler to determine which one you’re attempting to call, that’s why it’s ambiguous.

how does mojo do it

There’s plenty of things they do that users can’t do right now (take the Tuple as an example) but I guess this is probably a question for @Jack Clayton.

I'm not sure what's happening here, can you show me what type and MY_SIMD implementations look like?
