In reply to @gesee37 "Itried  posting this": Some people way back when wanted
to run the language by committee, Araq is a BDFL and said no. Whether that
project is worthwhile is up to you to evaluate.

Other than that, everything Ras said, plus, for a beginner:

1) Be careful of the macro trap, prefer obvious and simple code first. Nim is
good at that. Really applies for all macro-capable languages, including Julia.
2) Also be careful of the pointer/ref trapdoors, Nim can be written like a
value-oriented scripting language by default. It loves immutability and
stack-managed values. Use pointers and refs only when they're absolutely needed,
such as for your render backend. Your codebase will be simple and still
extremely fast.
