* math: Make function parentheses optional It's a bit annoying to use parentheses here because that requires quoting or escaping. This allows the parens to be omitted, so math sin pi is the same as math 'sin(pi)' Function calls have the lowest precedence, so math sin 2 + 6 is the same as math 'sin(2 + 6)' * Add more tests * Add a note to the docs * even moar docs Moar docca * moar tests Call me Nikola Testla
