Re: Argument lists

It might be better if function-parameter-names returned 4 values by
splitting its first value up into 3 separate values.  The required, the
optional and the rest.  This would make it easier for programs which
just want to print the parameters of a function, they wouldn't have to
both function-parameter-names and function-parameters (using the values
from the second to split up the values from the second).

If function-parameter-names gets changed that way, the spec has to make
it very clear whether the values returned can be bashed since people who
want just one value (all the argument names) are going to have to decide
whether to use nconc or append.
