Perhaps some simple heuristic of length (> 80 chars?) would 
suffice?
Or perhaps Error: no property 'IF_gray' for type 'ImageFormat' 
from module 'foo.bar'.

One of the most confusing errors to get is
> Error: no property 'IF_gray' for type 'ImageFormat'
when 'ImageFormat ' does have that property but it uses a 
different 'ImageFormat' (in another module) that doesn't.
