Uhm, point taken. Let's do as you say.
Actually, we could take the spirit of your suggestion (i.e.
gradualism) in this way:
1) In the next release, keep "set halt_on_error off" working as at
present but print something like
Warning: 'set halt_on_error off' is deprecated. Please use
'catch' to trap errors instead.
2) In the following release, remove it.
