-std=c++14 to g++ to enable C++14 instead of the current C++11 mode. C++14 does bring quite a few productivity enhancements that I've found myself needing very early in the game (to cite just one notable example: generic lambdas).
Additionally but less importantly (I'm new to the game so I haven't found myself needing those yet, but I'm anticipating), sorted by decreasing interest:
- It would be nice to be able to include Boost libraries. In "day to day" C++, Boost is virtually a must-have extension of the standard library.
- It would be nice to compile with optimizations turned on (not sure if it would really make a difference in any of the puzzles?)
- It would be nice to have g++5.x
Thanks for your time, and I think your site is pretty fun.
