Re: [Gretl-devel] members of lists returned from functions

Ah, there's a loose end here, in terms of behavior when a function
returns a list: what should happen if the list contains
one or more variables that have the same name as a variable that
already exists at the caller level?
What's happening at present can be exposed by this variant on
Sven's script:
function test(void)
series s1 = randgen(u,0,1)
series s2 = randgen(u,2,3)
list myl = s1 s2
print "in test"
print s1 -o
return list myl
end function
nulldata 4
loop 2
list check = test()
varlist
print "in caller"
print s1 -o
end loop
The last "varlist" produces:
Listing 6 variables:
0) const 1) index 2) s1 3) s2 4) s1
5) s2
which is not nice. It seems to me the second iteration should
overwrite s1 and s2 -- agreed?
Allin.
