[...] I am not sure what that mean. What is 'functional' in basic_string class template? May be we just need to define terms.
The fact that you can't change the template, just like all templates in C++. It is immutable, so metafunctions are strictly pure functions. Of course, basic_string doesn't perform a very interesting computation as a template, which is why it doesn't look very functional to you. But in fact, it does perform a computation. It takes a character type as input and produces a string type as output. You cannot change the input character type into the string type, which is part of why the template is functional.
[...] From that stand point I believed in my review (still do) that FC++ is just a toy not a Tool.
I wasn't talking about FC++ in particular here, but rather FP in C++.
Toy is something kids play with, Tool is something adults use to do a real job. [...]
