There was a recent thread here ("Efficient predicates for the standard 
library") in which the names "any" and "all" were discussed rather than 
"anytrue" and "alltrue."  Those are at least their common names in the 
functional programming languages I know, and it easily sidesteps the 
confusion that might be caused by having an "anytrue" without an "anyfalse" 
or an "alltrue" without an "allfalse."
