I absolutely agree.  I've been working hard to get the in-memory data 
representation for Xorn right, and the main thing which keeps me from 
defining PCB object types right now is that I haven't found a convincing 
data model for these yet.

The part of parsing a .sym/.sch file which can potentially become easier 
with YAML is as simple as a sscanf(3).  After extracting the value strings 
from the file, you still have parse and validate them no matter whether 
they have been stored in a .sym/.sch or YAML file.
