Runtime performance I was wondering about how option B performs once the JIT / AOT does the work, if it is basically the same as concrete implementation call? C# has...

@Tarmil, not that I know much, trying with sharplab, with implicit interface implementation (but not related to IWSAM), the IL can avoid `callvirt`, and also less IL code in the...

@kerams great point, and it sounds plausible. Although I'm wondering if it really matters to have that deferred since it is already identified as a tuple, which is most of...

Wouldn't haskell's `newtype` be a more explicit way to handle all the above (although without some of the properties we have with measures which can combine when using calculations)? I...

I think this makes a lot of sense (asking user to notice/remove ambiguity), it may also apply to the way DU members can shadow each others (where the error message...

@DemiMarie I think this would need substanciation if we could provide samples highlighting the issue. From discussions with seasoned F# developers, it seems recursive function or while loop with a...

for "simple F#" aim, since VB.NET and C# know about type extension, and defining those in those languages is a pain, and even worse in F# due to this feature...
