## Convenience template around the ``keepIf`` proc to reduce typing.
##
## Unlike the `proc` version, the predicate needs to be an expression using
## the ``it`` variable for testing, like: ``keepIfIt("abcxyz", it == 'x')``.
## the ``it`` variable for testing, like: ``keepItIf("abcxyz", it == 'x')``.
## Example:
##
## .. code-block:: nimrod
## var candidates = @["foo", "bar", "baz", "foobar"]
## keepIfIt(candidates, it.len == 3 and it[0] == 'b')
## keepItIf(candidates, it.len == 3 and it[0] == 'b')
## assert candidates == @["bar", "baz"]
