Modifiers:

• G: given a function, return a monad with takes intiial value and generates an infinite list
• ∇: swap args or min-by.
• ¤: next two as monad
• ¢: next three as monad
• ¦: next four as monad
• ¥: next two as dyad
• ©: next three as dyad
• §: next four as dyad
• €: each. vectorizes over the first vector, or if there is no vector, the first argument.
• δ: right-each. vectorizes over the last vector, or if there is no vector, the last argument. given a monad, max-by.
• ß: monadify a dyad by repeating the argument, or given a monad, sort-by.
• /: reduce a list by a function, or if given a nilad n, consumes a function after that and reduces all chunks of size n by the function. so /2+ adds all chunks of size 2 in the array given.
• ω: apply function over all overlapping pairs of list, or given a nilad n, gets all overlapping lists of size n and reduces the function over each

Syntax:

• 'a: one-char string
• "...": string literal
• any of 0123456789.: number literal
• ##: one-line comment
• #{: open multi-line comment, closed by }#. nestable
• }: close some structure that is open (map, list, etc.)
• [: open a list literal, closed by }: [1 2 3}
• γ: map over a list, closed by }. so γ...} acts the same as a monadic operator, use it just like any other.
