I've proposed this before (maybe around a year ago), except the checks were
done at parse time, rather than runtime. I much prefer that approach. If
I recall correctly, the patch was considered to be good, but not good
enough since it didn't handle all contexts (perhaps FOR loop were missing,
or something; I forget).

I've also proposed this, and it was rejected because it was a runtime
check, and some people don't like runtime checks.
