This now surprises me, since your last email about functions being 
created with 'de' instead of 'defun'.

This is because the elisp parser uses Emacs' 'read' function, which has 
; built-in as a comment character.  I'd assume that it is not possible 
to fix that state.

That, combined with me not yet understanding why the elisp parser works 
makes me think your best bet is to start with the Scheme parser.  That 
parser is quite simple (scheme.by) and could be updated for picolisp 
definition symbols.  semantic-scm.el has customizations which will then 
fix the comment syntax by obeying the syntax table for picolisp.
