incorrect wordings on sentence

[udohjeremiah]

This statement isn't correct and it's hard to understand what is meant:

tuple of argument concrete types.

A better way would be:

tuple of concrete types argument.

Which is easy to understand as a tuple that contains arguments that are concrete types.

[sostock]

Shouldn't it rather be

tuple of concrete argument types

Since we are talking about a "tuple of types", not a "tuple of argument"?

[udohjeremiah]

IMO the "argument" coming before "types" seems weird for anyone not verse with things.
