Ceylon take various source files in and generates a tree of files where
the names of the resultant files bear no obvious relationship to the
source. Moreover this is a many-to-many mapping. Effectively the
compiler creates an internal indexed database rather than per file/class
compilation products.

On the one hand this is so far from the C/C++/Fortran/D model that there
is no hope of compromise. On the other hand it maybe that the Ceylon
compilation database structure is actually very simple and can be dealt
with by having quasi-hardwired dependencies.

Database file names are module structured so it may be that the database
structure is deducible using a SCons scanner over the incoming source.

I would be more motivated to do something about this if there were an
Emacs mode for Ceylon. Currently they are only interested in using
Eclipse.
