I was thinking of something much deeper, something like:
@optional('eggs')
def spam():
"""
docstring with the corresponding doctests
"""
blah
And then, several things happen:
1. The testing framework ignores the doctests for the function
`spam`only if the package `eggs` is installed.
2. On startup, the function `spam` is defined only if the package `eggs`
is installed. In particular, tab completion would only show it if the
package is installed.
3. Documentation for the function is only built if the package is
installed.
I know this goes way beyond what you proposed, but on the other hand I
think it makes sense to distinguish if a package is installed or not at
more levels than just the doctesting.
