Any decent editor should be able to balance parenthesis for you.

That your library will require a validation to be executed at run-time
seems like it will be tedious to use.

A decent text editor can even balance your HTML tags for you.

Though you have a neat "DSL" like language for representing HTML
elements.  I'd suggest taking it one step further and creating a
machine that can read in a Python data-structure and with as few hints
as possible wrap it in the appropriate tags.
