Hi Erik,
your actual problem is the record type. You cannot have unique chars in
a non-unique list. Try:
:: *Record = {field :: *[*Char]}
Start = {field = ['abc']}
Have fun,

Re: [clean-list] Matrix operations
In Clean 2.4 on Windows, with the following accepted type:
:: *Record = {field :: [*Char]}
All of the following alternative start-rules ...
Start = {field = []}
Start = {field = ['x']}
Start = {field = undef}
... result in the following uniqueness error message:
"argument 1 of Record" attribute at position indicated by ^ could not
be coerced ^ *[*Char]
I don't see why even undef would have a type that is not general enough.
Does anybody have any idea how I could fill this record?
