Dear NCL Developers,

I suppose that the following should not happen. Isn't it a bug?
We are told that variables inside a function have local scope, and
this unusual feature can lead to a lot of headaches. Any solutions,
other than "local a" or using another variable name than "a"

ncl 0> a=5
ncl 1> function testme(a,b,c)
ncl 2> begin
ncl 3> a=2
ncl 4> return(1)
ncl 5> end
ncl 6> print(""+a)
(0) 5
ncl 7> print(""+testme(a,1,2))
(0) 1
ncl 8> print(""+a)
(0) 2

Thanks,
saji
