Sorry, another feature request. Would it be possible/a good idea to add a way to get the type of a named parameter?
Certainly it's possible. Not sure if it's a good idea. Is there a use case? Some people are complaining that the library is already heavy artillery where none is needed.
Mostly it would just be for convenience. For example, if you want to copy a parameter to a local variable, or get the iterator type for a container parameter, you can move the implementation into a separate template function which will know the type. It looks like the library is designed so that if you want to do anything non-trivial, you need to do a further function forward. I guess this is not necessarily a bad thing, since it keeps it simpler. The one use that I can think of that can't be done this way is if you want the return type of the function to be dependant on the parameters. Daniel
