Yes, you could use it for one liners.

It remembers previous commands, so you can do more than one liners.

Since many popular modules are packaged in the executable, the code can
make use of them for more sophisticated, multiline operations with
variable assignments along the way to a result.
For someone learning Perl, this can be a friendly environment for
testing syntax.
The idea is intended to be the same as for other dynamic languages, e.g.,
Python and Ruby, where such an interactive environment is a useful part
of the overall development toolkit.
