Yes reading this make me wonder if the best thing to do is not often 
to just show the actual line of code (all the more that now -- or 
soon -- line and column information is available). For C++ and 
templated code, instead of showing the full function call 
with all types expanded, it would be nice to see the actual line 
of code and a trace of the template parameters and typedefs...
That does not remove the need for tree-pretty-printing but might 
improve the error messages.

Caveat: the line information should be 100% sure for doing this.

Am I overlooking some difficulty ?
