We'd like to do type conversion live and throw an error.
We don't want to throw an error when the parameter doesn't exist but return the default value. Ensure that the behaviour is tested.
It's not actually a fd leak, but might as well do it properly.
Having typed input parameters on the command line seems a bit overkill and leads to a poor UX. We already define the type of the parameter in code, we can keep that as the canonical type we want and coerce strings from the command line into the right type. Fixes: #102

Error: Should be true
Adding more details can help understanding what's going wrong, eg.
Error: Should be true

Specifying an input parameter on the command line now looks like:
