"That's Numberlang!"

Numberlang is an esoteric programming language that uses numbers for sumbols (variable names, function names, etc.)

There are three types of expressions in Numberlang:

• Numbers, for example 100, 0 or 237816.
• Tuples, for example (1 2 3) () or ((1 2 3) 4 (5 6))
• Function calls, for example 10 < 1 2 3 (in general [function symbol] < [argument] [argument] ...)

Some common function symbols:

• 0: Get variable 0 < [variable symbol]

• 1: Set variable 1 < [variable symbol] [value]

• 2: Sum 2 < [number] [number] ... returns the sum of all the numbers

• 10: Print 10 < [value] [value] [value] ... prints all the numbers inputted as their ascii equivalent (tuples get flattened)

• 11: Converts the value to a string (tuple of numbers) 11 < [value]

• 30: Create function 30 < [function symbol] [arguments] [expression]
