Returns specified number of first elements in input set and discards everything else.
A typical usage scenario is to have limit \`1\` which ensures that the output set only contains a single element.

### Use For

- restricting elements to a single element
  (e.g. for \`click\` actions, especially when filtering yields more than one element and
  they are functionally equivalent)
- returning sampled data of fixed length
