const char *foo2 = foo.c_str();
Is there a reason why not do const_cast?
const char *foo2 = const_cast<char*>(foo.c_str());

Um, because it is an ugly hack? :-)

Seriously, if you could write

std::string str="hello";

char *q = const_cast<char *>( str.c_str() );

*q = 'B';

where would that leave str? Suppose you used that non-const pointer as a
target for a string copy operation where the source length exceeds the
allocation of the string? Nothing good can come of that kind of hackery.
