Because they return function objects, they can be used in certain types of function composition to construct more complicated and powerful expressions.If func is an object of type Operation and c is a constant, then bind1st( func, c ) is the same as the binder1st class constructor binder1st...
You can specify arbitrary functions as a string with theinlinecommand and pass them to the function function routines, but this command is difficult to use, particularly to separate the many different types of parameters, including the arguments to the inlined function and the function...
