funny functional language

becomes_zero = .==0;
is_even = (%2) becomes_zero;

main = 11 is_even;

// 11 (%2 . ==0)
// 11 % 2 == 0

Function results

value	function	result	example
`number`	`+number`	their sum	`1+2 // 3`
`number`	`-number`	their difference	`1-2 // -1`
`number`	`*number`	their product	`1*2 // 2`
`number`	`/number`	their quotient	`1/2 // 0.5`
`number`	`%number`	their remainder	`11%2 // 1`
`val1`	`<~val2`	`val2`	`1<~2 // 2`
`val1`	`==val2`	`true` or `false`	`1==2 // false`
`number`	`>number`	`true` or `false`	`1>2 // false`
`number`	`<number`	`true` or `false`	`1<2 // true`
`number`	`>=number`	`true` or `false`	`1>=2 // false`
`number`	`<=number`	`true` or `false`	`1<=2 // true`
`any`	`!=any`	`true` or `false`	`1!=2 // true`
`string`	`+string`	concatenation	`"a"+"b" // "ab"`
`string`	`*number`	repetition	`"a"*3 // "aaa"`
`string`	`/string`	split	`"a,b,c"/"," // ("a", "b", "c")`
`tuple`	`+tuple`	concatenation	`(1,2)+(3,4) // (1,2,3,4)`
`tuple`	`*number`	repetition	`(1,2)*3 // (1,2,1,2,1,2)`
`tuple`	`-function`	filter	`(1,2,3,4,5) - (<3) // (3,4,5)`
`tuple`	`*function`	map	`(1,2,3,4) * (*2) // (2,4,6,8)`
`tuple`	`/function`	reduce	`n add = +n; (1,2,3,4) / add // 10`
`bool`	`&bool`	logical and	`true&false // false`
`bool`	`\| bool`	logical or	`true \| false // true`
`function`	`+function`	composition	`(%2) + (==0) // "is even" function`
`function`	`*number`	composed with itself n times	`(%2)*3 // (%8)`
