Seems like in certain contexts the compiler cannot deal with the 'list'
using namespace boost::mpl;
typedef begin< list<int> >::type t;
typedef lambda< list<int> >::type l;
# 78: : lambda_impl< F<T1>,Tag,true_ >
# Error: ^
# internal compiler error (report to <cw_bug_at_[hidden]>)
# while executing in file 'CTemplateClass.c' line: 270
Weirdly, the numbered form ('list0...n') seem to be fine:
typedef begin< list1<int> >::type t;
typedef lambda< list1<int> >::type l;
I might get to the root of it and provide a workaround in the core of the
library, but it definitely looks like a nasty one.
Meanwhile, I suggest you to switch to using numbered lists/vectors.

Not necessarily useless. I wouldn't be surprised if CW9 still has it.
