The standard module for type list manipulation there are metafunctions such as
staticMap and ReplaceAll and EraseAll, but there is no staticFilter.
staticFilter is good, because filter, like map is foundamental operation of
functional-programming like lists. Also, it is more general-purpose: EraseAll
can be implemented in terms of staticFilter.
As a use-case, we may use the function as follows:
alias staticFilter!(isInputRange, R1, R2, R3) InputRanges;
