It would also be possible to add a bit of syntactic sugar to allow: enum color {...}; template<color> some_class {}; template<template <typename,int> class T> struct tt_class {}; template<typename A1,T A2> struct dependent_class {}; BOOST_TYPEOF_REGISTER_TEMPLATE(some_class, (enum(color)) ); BOOST_TYPEOF_REGISTER_TEMPLATE(tt_class, (template((typename)(int))) ); BOOST_TYPEOF_REGISTER_TEMPLATE(dependent_class, (typename)(dependent(0)) );
Unless I am missing something, there may be some problems with this.
The first thing that needs to be done is pasting prefix and suffix to allow handling something like "unsigned int":
PREFIX_unsigned int_SUFFIX
However doing the same with, say, "enum(color)" would have to produce:
PREFIX_enum(color)_SUFFIX,
And I am pretty sure some preprocessors (for example GCC) would have a problem with pasting anything to ')'.
But maybe you have something else in mind?
My idea was to let _SUFFIX expand to nothing, but you are probably right in that this is less portable. I have only tested it with VC7.1. I'll give it a go with GCC as well, to see what happens. Regards, Peder
