You could do what some of my anal-retentive (and english-imparied) coworkers
took to doing: line up your commas or semicolons in the parameter lists with
the parentheses! eg:

  procedure Pop
    ( Item :    out Element_Type
    ; List : in out List_Type
    ; Flag : in     Boolean
    ) ;

Another advantage of this that they touted is that a parameter may be added or
deleted at the w/o having to worry about dealing with the "no comma after the
last parameter" rule.

I was always quick to point out that they just moved the problem to the first
parameter, and that it is very un-english like. But their overly mathematical
minds just didn't care.

What I actually prefer myself is the same as above, but with the semicolons
where you'd expect them to be.
