A single function assembler suffices to assemble all the different types of functions in Sling except for scale.
The scale function requires a special assembler because internally a Scale object takes five parameters in its constructor, and the Sling language allows for only two arguments in the scale function. The Sling parser always sets the first three parameters of a Scale object to 0, t, 1.
