[wingide-users] An idea for better auto-completion

Wing already does this for you.
If you use assert(isinstance(*variable*, *type*)), Wing will pick up on the
assert, and knowing that the assert will not allow processing to continue
past this point unless the assertion is met, it will presume everthing
following will treat that variable as that type and give you appropriate
There is a section in the documentation which, embarrassingly, I also
overlooked the first time, that also suggests that you can minimize problems
with circular imports by wrapping this code in if __debug__: blocks. If,
for instance, your module does not NEED to know that your variable type is
an instance of wx.TreeCtrl because your currently edited page in the module
doesn't import wx.*anything*, but you want to use code-completion to access
barely-remembered wx.TreeCtrl methods and variables, you can use
In this case, if I understand the specifics correctly, Wing will know to
find the TreeCtrl object in wx and provide you with appropriate assistance,
and of course when you run the app, that import will be attempted, if it
hasn't already happened. But when you run your Python with the no debug
flag -) and all if __debug__ blocks and assert() statements will be
overlooked in the compile.
