Previously, func.compose only supported two functions, as in:
compose(print, string.upper)("hello") -- prints "HELLO"
This commit enables any number of functions to be composed by internally
leveraging tablex.reduce to repeatedly apply functions.
For example:
compose(bind1(add, 10), bind1(mul, 5), bind(div, _1, 3))(9)
-- prints "25"
One can also pass functions as a table:
compose({ bind1(add, 10), bind1(mul, 5), bind(div, _1, 3) })(9)
-- prints "25"
