* General portability note:
|
|
* MSVC mis-compiles explicit function template instantiations.
|
|
* For example, f<A>() and f<B>() are both compiled to call f<A>().
|
|
* BCC is unable to implicitly convert a "const char *" to a std::string
|
|
* when using explicit function template instantiations.
|
|
*
|
|
* Therefore, avoid explicit function template instantiations.
