Comment(by tschaub):

 Wish I had weighed in on #2979.  I think if we are going to be adding
 convenience functions to the layer, they should be thought out in a bigger
 picture context.

 The proper way to accomplish this (in my opinion) would be more like:

 In the case of an attribute filter, you would write:
     layer.query("foo = 'bar'")

 And if we shipped with a {{{geometryType}}} filter function, you could do
 something like:
     layer.query("geometryType(geometry) = 'Point'")
 (This would take some special work to test {{{feature.geometry}}} when
 {{{feature.attributes.geometry}}} is not present.)

 Anyway, I agree with Eric that it is easy to iterate through
 layer.features for now.  If/when we add convenience, let's try to do it
 without a new method for each case.
