Should ParseTex return an error value?

[Wyatt915]

Currently, any (nonfatal) parse errors produce an <merror> tag in the mathml tree without complaint. Would it be useful to know if nonfatal parsing or tokenization errors occurred by bubbling up an error value?

It would be helpful to know while building my blog if some LaTeX is broken, rather than find out about it in the preview, or worse, after it's deployed.

Yes, I'd prefer to get any parsing errors explicitly, as the half-baked MathML with its error tags won't be useful.
