Consider allowing arrays to be bound to list options.

[imbriaco]

Command options can be of type list which means that they can either be specified multiple times or can be passed a comma separated string in order to set more than one value for the option.

imbriaco:optdebug -l foo1 -l foo2 -l foo3 ...
imbriaco:optdebug -l foo1,foo2,foo3 ...

It would be nice if you could also directly bind an array, e.g.

seed '{ "foo": [ "foo1", "foo2", "foo3" ]}' | imbriaco:optdebug -l $foo env
