Use typeof(setAge).stringof to get something you can then parse 
to fet the names.

My web.d has a function to do it:

InfoImpl is here:

https://github.com/adamdruppe/misc-stuff-including-D-programming-language-web-stuff/blob/master/web.d#L1956

It gets typeof(func).stringof then does a rudimentary parsing to 
get the argument names and default values out as arrays of 
strings.
