digitalmars.D.learn - Get list of public methods of struct

I looked at both "traits" and "std.traits".

getVirtualFunctions and getVirtualMethods are closest I guess, 
but they don't seem like general purpose due to "Virtual" part. 
(Wouldn't it work if a method was final?)

I saw "FieldNameTuple" in std.traits, but that doesn't seem like 
a proper solution.

I want to use a mixin and foreach to generate a piece of code, 
that selects which method to call based on given parameter. So, 
the generated code will be like,

if( param == "woof" )
     myStruct.woof();
else if( param == "meow" )
     myStruct.meow();

woof and meow are the methods of defined struct.

You can loop through __traits(allMembers, YourStruct) and check 
protection, type, etc.

__traits(getMember, YourStruct, "some name") gets one method in 
particular. allMembers returns a list of name strings.

If there's any risk of the same function name being used for both public and
private functions, then __traits(getOverloads, ...) is going to need to be
used rather than getMember, since getMember only gives you one of the
overloads.
