Class enthought.​block_canvas.​block_display.​execution_model.​StatementWalker

Walks code ast to find all nodes that will be used to create statements for the ExecutionModel object. There is a method for visitAssign in order to capture output binding information for the function calls returned from FunctionCall.from_ast which cannot return this information. For functions with no output binding information, the visitCallFunc method will capture the ast.

FIXME: Currently, this will only find function calls and constant expressions. Need to add code to visit general expressions, groups, etc.
