I definitely agree that performance is best measured, not guessed about. Ho=
wever, the way I see it, this restriction is (at least for my use case wher=
e I know I don't need tagged types) at best making the compiler work much h=
arder to see that it can devirtualize the function calls and at worst makin=
g my code run slower with no benefit - other than providing a slightly nice=
r syntax.

I assume there was some rationale behind the decision, though, so I'd be in=
terested if anyone has any insight on that.

As a side note, I did do a test at one point and if I remember right, the c=
ompiler didn't devirtualize the custom indexing even for my simple test. I'=
ll have to see if I can recreate the test and try with a newer compiler tho=
ugh.
