Compiler Bug

[Alex]

Comes from doing foo!(Alias!([AliasSeq!(A,B,C)])) or just 
foo!(AliasSeq!(A,B,C)) when trying to pass a type for A, removing 
A works. A is a template parameter from another template.

Shouldn't the errors give line numbers and source code where the 
error ooccured rather than a bunch of rather useless information? 
I realize it is a fault but if it can spit out that info maybe it 
should keep track source code(the compilers).
