Also kinda in the process of removing exceptions, in order to 
converge upon the custom WebAssembly druntimes that float around. 
Our exceptions were manually allocated anyway with a bearing on 
the catcher.
A pattern that can help is the fail() bit a bit like std::file or 
FILE*. It's the same morass of error codes and boolean a bit 
everywhere, but we can hide it from the library user.
For parsers, having popBack() throw is expensive so it can be 
valuable too to lessen exception usage.
