Adding import fmt to tour #38 breaks it #173

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem?
1. Add fmt import to tour #38

What is the expected output? What do you see instead?
A "debug" line, then a picture.

What I see, which is quite unexpected: How does an import break a package?!

Found out that this is due to magic in the tour, so this can be closed.

There may be a more clever way to process the emitted image, but we're not 
doing it yet.
