I propose we enable compilation of the following SRTP function:
let inlinef(t:^Twhen^T:(member Foo:int ->int)and ^T:(member Foo:float ->float))=
printfn "%d"<|(^T:(memberFoo: int -> int)(t,0))
printfn "%f"<|(^T:(memberFoo: float -> float)(t,0.))
(This could also be adapted to the simplified syntax introduced in F# 7)
The existing way of approaching this problem in F# is to handle reference types or immutable structs by passing them as two separate arguments, each with its own SRTP type parameter. However, this approach is not feasible for mutable structs or structs following the builder pattern.
Pros and Cons
The advantages of making this adjustment to F# are primarily enhancing the language's consistency and expanding its capabilities.
The disadvantages of making this adjustment to F# are potentially introducing more complexity into the compiler's implementation.

[v] This is not a question (e.g. like one you might ask on StackOverflow) and I have searched StackOverflow for discussions of this issue
[v] This is a language change and not purely a tooling change (e.g. compiler bug, editor support, warning/error messages, new warning, non-breaking optimisation) belonging to the compiler and tooling repository
[v] This is not something which has obviously "already been decided" in previous versions of F#. If you're questioning a fundamental design decision that has obviously already been taken (e.g. "Make F# untyped") then please don't submit it
[v] This is not a breaking change to the F# language design
I or my company would be willing to help implement and/or test this -- I'm willing to test, lack necessary bandwidth and expertise to implement it by myself
