You can use a function lambda:
auto fp = (real a) => cos(a);

"a => cos(a)" to work.

Interesting. You have to put real because there is also a float
and double version of cos.
Even if there are no overloads, you'd still need to specify the
type. That's because `a => cos(a)` is not a function, but a
function template, and therefore can't be store in a variable.
