The element of runtime reflection that is the most useful is something along the lines of "here's function, here's a list of arguments, go call this function with those arguments".

Having to do this by reflection is a problem in principle solvable by types. Here is a function of type (A, B, C) => R, and here is a tuple of arguments of type (A, B, C), go call this function with those arguments.

Most programming languages make it hard to easily express those constraints so reflection is used instead.
