I'd like to go further: find the template arguments and the
function arguments and return types. Looking at __traits and
std.traits, it doesn't seem feasible, but maybe I overlooked
something?
You can use TemplateArgsOf
https://dlang.org/phobos/std_traits.html#TemplateArgsOf
to get the template arguments.
For the stuff below, I think you can't just use foo, it has to be
a specific foo!T.
You can test if it's a function
https://dlang.org/phobos/std_traits.html#isFunction
You can get the Parameter and Return types
https://dlang.org/phobos/std_traits.html#Parameters
https://dlang.org/phobos/std_traits.html#ReturnType
You can get the names of parameters
https://dlang.org/phobos/std_traits.html#ParameterIdentifierTuple
