Hi Samuel,

if you declare a generator with the empty list of source type, it will accept anything.

As for leaves, typically top-level generators, such as for EXE type, are composing - they
can accept multiple sources of any types, and they work by trying to convert each source
into a type they natively can consume - e.g. into OBJ. If you generator can do this
for a specific source, directly or indirectly, it should be invoked.
