this might work as you hope,
('p'~ , 0 $ 'p' =.. ]) 'erling'
if not,
(3 : 'p' , 0 $ 'p' =.. ]) 'erling'

Hi all !
I was trying to understand how thecopula verbs =..and=:: works in tacit
expressions.
(p , 0 $ 'p' =.. ]) 'erling'
|value error: p
| (p,0$'p'=..])'erling'
('p' =.. ]) 'erling'
erling
(p , 0 $ 'p' =.. ]) 'erling'
erling
(p , 0 $ 'p' =.. ]) 'fredrik'
erling
(p , 0 $ 'p' =.. ]) 'fredrik'
fredrik
(p , 0 $ 'p' =.. ])
'fredrik' , 0 $ 'p' =.. ]
I wonder if it is really useful in tacit expressions, and in that case,
how it can be used.
It is only used to set variables outside of the expressions, not to use
the variables in the expressions?
Useful in for example debugging?
This is from the documentation:
"The copula verbs =..and=:: are similar to their corresponding copulas
but are syntactically dyadic verbs and may be embedded in tacit
expressions."
Cheers,
Erling Hellenäs
