I have the following program. It also includes the non-template

will see the compiler errors. The errors are also shown below. Do you
know what is wrong? Is it a bug of the compiler?
BTW, I use g++-3.4.
I corrected the error by adding template keyword. But I don't
understand why "template" keyword is need. Would you please help me?
Because when the compiler first parses your function, it doesn't know
what type T is, and so it cannot know that 'T::(something).as' is a
template and 'T::(something)/as<int>' is valid syntax.
This is standard C++, go google up 'templates two-phase name lookup'.
