Here's my own copy of the main Nim repository. See original at https://github.com/nim-lang/Nim

• Fixed: main module name can start with a digit. Proabably also with underscore, but that needs test.

Some notes...

• No % and // ops, only mod and div. Aha, there's %%. Where then //? (Aha, rationals. Never-used :) Can define own div)
• Other ops... we'll see. Documentation on expressions is absent, or split over different parts.
• Parameters are const. WTF! I have to create a mutual copy not only for complex data, but even for ints! Yes, this feature sucks but I see the idea and not clear how to fix it. Also weird: variables -- var i: int, arguments -- i: var int.
• discard is disgusting. Why not skip?
• incl for sets must be add (as well). OK, can have alias.. probably.
• No loop/forever, again stupid while true. GSD it's not True. Ok, can be defined with template.
• Probably must be reverse: @[...] <--> [...]. Aha, @ is op. Interesting. But still not sure if wise.
• const A=1,B=2,C=3 should work!
• as well as var a=1, b=2. Let's do it!
• really annoying that you can't write a=-1 or b+=+1 or c=@[] -- there must be ' ' after '='. This should be fixed!
• foldl, map, split, join, sum, ^ (power) %% and // for ints must be in system module. Also << >> & | ~ (xor)
• var a: enum A,B -- internal error pfffff. Reported.
• also error with a=a*b vs a*=b under overflowchecks.
• type S = 0..1 \n var good: array[S,S] = [S(0),S(1)] \n var bad: array[S,S] = [0,1] -- should work too! in definition
• what's wrong with for i in 0..10: if a[i]>0: echo a[i]; t+=a[i] else: echo "!",i? what can be misunderstood there?
• Ids have case-sensitive first letter, the tail is case-insensitive and underscores _ inside it are ignored. Wow this is weird!
