OK, I'll rephrase my objection.
Is the proposed 'import sin,cos from math' really so much more
convenient than 'local sin,cos = math.sin,math.cos' as to justify
two new keywords?
Personally I don't think it is clean and clever to make war veterans
like `sin` and `cos` local, but let's not cloud the syntax issue.
