I don't mind having to add -std=c++11 as much as dealing with its incomplete
implementation. Still have to use the pcre library for regular expressions.

Waiting gets me nervous, so in the mean time I'll rather write more D.
- And then another roadblock: the compiler says, "hey, buddy, std::hash
hasn't been specialized for cache_key_type yet, so it doesn't know how
to compute the hash value of the key, and so I can't instantiate that
template for you!".
Oh, yes, been through this. Why is there no hash function for const char*?
The second thing is that not everything has a string representation that can be
output on screen without doing extra processing. to_string just barely started
working in newest MinGW. If you don't have that available and ask for a
different but still _simple_ way to convert a number to string, you are shown
the good old stream code:
std::stringstream ss; ss << number; out = ss.str();
Seriously? If I could at least chain that...
out = std::stringstream(number).str();
Unfortunately, no. So I end up adding my own functions in every project for many
trivial tasks, which should be doable out-of-the-box with minimal effort. Yep,
to_string helps, but C++11 and its complete support are coming much too late.
Therefore, being quite impatient, I'd also like to say thanks for D. :)
