Well, you can sneak things by using nested sequences.

function x(object things)

and call like:
z = x( {"yes",34,8.9,{2,3,5}} )
z = x( "no" )
z = x({ {"yes",23},{maybe,98,65} } )
z = x(2)
z = x({2.6.8.12,5})

As long as x can figure out what is sent, it's do-able. I do it in strtok. Most 
functions in that lib can accept a string or a sequences of strings as the first
parameter, an atom or sequence of atoms as the third parameter, and 
parse() can take an atom or string or sequence of chars as the second 
parameter.
