Thanks Joost. ({grin} at RMGir)

I had a 'feeling' it was a context problem as noted. I just didn't know what to do about.

So, spelling out what is going on here (just incase I'm not the only DSOB that reads this):

With my $var = all(); when all() checks wantarray() to determine its calling context, it gets SCALER and therefore returns the count of the states that matched the condition.

With my ($var)  = all();, wantarray() gives ARRAY so all() (or probably eigenstates()) returns the list (in this case containing just one value) that matched the condition.

I know I'll be (rightfully and usefully) corrected if this is wrong:)
