Module enthought.​block_canvas.​function_tools.​function_call

Class that holds information about how a function is to be called and provides methods for creating python code strings that will call the method with appropriate arguments.

It is useful for displaying UIs for functions on the workflow canvas.

Note: It may also be more fundemental -- for example part of a Block node

to make it easier to edit inputs/outputs on nodes and also to coordinate text and graphic views of a workflow. This isn't clear yet.

fixme: Output variable bindings can only be a valid python variable.

We need a trait to represent this restriction.
