defining functions

[Michael Somos <somos@grail.cba.csuohio.edu>]

Spurred by a recent message to par-dev, I have realized that it is
possible to define more than one function on a line. Here is the way :

gp> (a()="a");b()="b"
gp> ?a
a() = "a"
gp> ?b
b() = "b"

Note that there is a need to do something to avoid the following case :

gp> a()="a";b()="b"
gp> ?a
a() = "a";b()="b"

The definition of a() does not stop at the ";". With the previous use
of enclosing parenthesis, it stops before the ";". Shalom, Michael
