Basically, we keep track of the template parameter lists that we've parsed and then provide those to the various Action routines that will end up constructing templates, e.g., ActOnTag for creating class templates (but not enum templates <g>).<br> <br> The Depth/Position stuff is working toward a fix in the type system. Basically, template parameters in the type system will be identified by their kind, depth (= the number of enclosing template parameter lists), and position with in that template parameter list. For example, 'T' in<div class="Ih2E3d"> <br> <br> template<typename T> void foo(T);<br> <br></div> is a template type parameter with depth=0 and position=0. That's the canonical type for 'T', and we'll use some sugar to give it the name 'T'. That way, we can quickly match the declaration above with the definition below<br> <br> template<class U> void foo(U) { }<br> <br> - Doug<br> </blockquote></div><br>I just merged my patches onto yours and started stubbing out some declaration classes.
