PQL can silently ignore typos

[seebs]

What's going wrong?

Rows(colum=3) does not produce an error.

What was expected?

Probably a diagnostic. When something's a field name, I believe we report if there's no such field, but when something's grammatically field-name-like in the PEG grammar, but not actually used as a field, it may be ignored silently.

Steps to reproduce the behavior

See above.

Information about your environment (OS/architecture, CPU, RAM, cluster/solo, configuration, etc.)

N/A.

I'm still thinking about this but probably going to try to address it shortly in passing as part of looking at adding some functionality.

this will probably get solved as part of plugin work... but let's revisit and make sure.
