Sorry for my French version.

I cannot see what you're suggesting "practically" as a frontend.
I don't think having another parser next to the first one for better error
messages is a serious option? I would not like to put another parser that
need to be kept synchronized with the first one. So either it is
integrated or linked with the current parser, or it is not there?
Out of the parser, the only information is the offending token (embedded
in the error string) and the character number in the string, that is quite
small a clue to give a hint.
