Yeah, the use of multiple classes in separate files does create more  
overhead than using only functions in one file.

We can certainly benchmark it once it's ready; I'd be happy to  
include your final product in the Solar_Markdown benchmarks for  
comparison.

Heh.  :-)  It's optional, and turned off by default iirc.  I have it  
mostly to standardize whitespace, not to fix HTML.  (Hm, might also  
be a solution to the "invalid markup" problem you note above.)
