So we pay for the feature even if we are not using it?  It's worth
it as far as I'm concerned, and perhaps even cheaper than doing
a call to a builtin function like length() or size().

The other option would be what? March up the parse tree when you
encounter an end in a subscript context and insert explicit save/restore
pointer commands for each identifier you encounter?
