| | A example of a function f that accepts optional-parameters. Besides the required parameter rp, the function accepts an arbitrary number of additional parameters,
the list of which are bound to the formal parameter optional-parameter-list. The function optional-parameter
from the LAML general library accesses information from optional-parameter-list. In case an optional parameter
is not passed, the default value (the last parameter of optional-parameter) applies.
