stricttex – Strictly balanced brackets and numbers in command names

This is a small, LuaLaTeX-only package providing you with three, sometimes useful features:

• It allows you to make brackets [...] “strict”, meaning that each [ must be balanced by a ].
• It allows you to use numbers in command names, so that you can do stuff like \newcommand\pi12{\pi_{12}}.
• It allows you to use numbers and primes in command names, so that you can do stuff like \newcommand\pi'12{\pi '_{12}}.
