PS: A #haltIf: aBlock message would be handy too :-)

already there:

1 haltIf: [1<2].

1 haltIf: [:rec | rec isInteger].

1 haltIf: (1<2).

1 haltIf: #doIt

especially putting a symbol is very useful. e.g. you can out the selector of the test and then even

put a haltIf: into system methods called all the time. (e.g. collections).
