On a fresh session, I was able to duplicate everything you said, and reverting
back to your original version was needed. But then the more advanced objects I
tried it on started to refer to dElEtEmE instead of the "right answer".
Switching back to my version solved everything... restarting and not trying
your 'a' OO2def 'base' test before that variable was assigned, produced the
correct results too.
Here is a commented version...
OO2def=:2 :0 NB. m: string of method/field, n: locale number (boxed
optional)
NB. returns function that is either method or Get-field for the member m__n
nm=.m refname n
".'t=.',nm NB. trash variable
if. 0=4!:0<'t' do.t=.".bind nm end. NB. if current value of field is noun,
return field getter/reader
(5!:1<'t')5!:0
)
A simple example of usage... is a fix for the bug I reported earlier. Self
contained version of Closure.
foo=: 2 : 0
a=. cocreate''
f__a=: u
S__a=: n
t__a =: 4 : '] S__x=: S__x f__x y'
a & ('t' OO2def a)
)
] f =: + foo 3
] (<,'8')&t_8_
f 2
5
f 5
10
f 0
10

Odd, in a fresh session, I get:
'a' OO2def 'base'
|value error: a_base_
9!:14''
j601/2006-09-04/09:20
I've tried this on two different machines -- same behavior.
Also, if I define 'a', it still doesn't work right:
a=:3 :'const+y'
'a' OO2def 'base'
3 : 'const+y'
