Hmmm. The last simpler structure I suggested, which is basically the one
used in your code before the update, does check for the structure error
first. The only drawback is that the condition is only evaluated when
needed, which is an issue we can cope with, IMO.

ISTM that the consistent message by Robert & Tom was to provide simpler
code even if the user experience is somehow degraded, as they required
that user-friendly features were removed (eg trying to be nicer about
structural syntax errors, barking in interactive mode so that the user
always knows the current status, providing a detailed status indicator in
the prompt...).

Now committers can change their opinions, it is their privilege:-)
