23 | * General portability note: | |
24 | * MSVC mis-compiles explicit function template instantiations. | |
25 | * For example, f<A>() and f<B>() are both compiled to call f<A>(). | |
26 | * BCC is unable to implicitly convert a "const char *" to a std::string | |
27 | * when using explicit function template instantiations. | |
28 | * | |
29 | * Therefore, avoid explicit function template instantiations. | |
