Possible ideas for next version (v0.3b)

Stack (STK.NEW, STK.PUSH, STK.POP, STK.TOP)
Gamepad detection (GPAD.*)
Some new example minigames. Ideas:
- Pacman clone
- Breakout clone
- Combat clone
- Convert my old C++ game "Labirinto do Dragão" (aka "Dragon Labyrinth") to PTML

Possible ideas for any future versions

Function support
Complex expression evaluation
Some kind of PTML standard library
Optional obfuscation format for PTML source code
Compilation of PTML source code into bytecode to improve runtime performance
More user-friendly documentation
Some kind of test suite for internal testing
