How about something like the following rework of the capture/hypotheticals thing: You're allowed to declare variables beginning with a 0 inside rules, eg $0foo or @0bar. Rules by default capture to $0rulename. Variables that begin with a digit are rule variables, all rule variables are always hypothetical, no other variables are hypothetical. Drop the 'let' keyword. -- ralph
