[Dancer-users] Problem with an open filehandler within the route

[sawyer x]

That's odd. The routes are just saved and rerun every time, but they're
enclosed scopes so that shouldn't happen.
I'm probably too tired and not smart enough to clearly see something simple
that's happening here.

My suggestion is: close the damn filehandle when you're done with it! :)
