tree-sitter is a GLR parser. This makes sense for a general 
purpose text editor like Atom and Neovim.

It can handle more grammars
It can handle grammars that require fixups in the parser better 
(e.g. C++)
It can potentially give better syntax error reporting

But does come at a cost, and these benefits might not apply to an 
editor that handles just one grammar (Like a D IDE)
