I propose to add the following function to the imp module:

exists(modulename) Test whether the named module can be found. This method should be used when you want to perform alternate actions depending on whether a module is available. Returns True of the module can be found and False otherwise. A True return value does not guarentee that the module will be importable. The module will not be imported as a result of calling exists, but parent modules may be. If a dotted module name is given, then parent modules will be imported if they haven't already been imported.

+1, but shouldn't "parent module" really be spelled "parent package"?
