I thought about lambdas before I wrote my answer but I thought decltype was and is more conventionally used for that purpose?

Can you elaborate what you envision there? For reference, a lambda in C++ might look like this:

    auto sqr = [](double val) { return val * val; };

(The lambda expression is technically only the part after the =, but storing it into a variable is common enough).

How would you use decltype here?
