notall

True if the block returns false for at least one element.

Synopsis

my $bool = notall { BLOCK } @list;
warn "some missing" if notall { defined } @values;

For each element notall sets $_ to that element and calls the block in scalar context. It returns true as soon as the block returns false for any element. An empty list yields false.

What you get back

1 if at least one element failed the block, 0 otherwise.

Examples

my $incomplete = notall { defined } @row_cells;
warn "stale" if notall { $_->is_fresh } @entries;
my $false = notall { 1 } ();             # 0 — nothing to fail
