Yes, this is also true for setting a parameter:

Car new -doors $amount

If $amount contains a dash, it'll do a method call.

Well, "contains" is too strong, "starts with a dash followed by alpha" is precise.

Sorry, yes. I need to check still what 2.0 does with:

Car c1 $a

where $a starts with a dash.

Class Car -parameter {{doors:integer 4}} Car c1 -doors -2 Car c2 -doors a-b

to trigger an error on "c2", or better define your own checker "posint"

Class Car -parameter {{doors:posint 4}}

to get already errors on c1.

I think these are fine. Errors when given a parameter of the wrong type are totally expected, and cannot be abused to execute code with bad values.
