Memoizing a templated version of a function doesn't seem to

A template isn't a function, it's just a recipe to define a
function given one or more compile-time values or types. So
memoize works if you instantiate in some way the template:

Instantiate the template first. Either:
n = memoize!(test2!int)(n);
or:
alias test2!int itest;
n = memoize!itest(n);
Actually I'm a little surprised this doesn't work:

I think your second equivalence is wrong:
