I have data objects where each component is a labelled field through which I access or modify it.
Wading into the labelled field debate...
I have found that using the labelled field update syntax can lead to difficulties in changing the underlying implementation of a type.
Yeah, interesting this topic came up exactly when I got mad with record updates. I'd like to fill in a record from a file which contains labels and values. I'd like to give the gist of this operation as a list of pairs: [("label1", label1), ("label2", label2), ...] and abstract away the operation of updating the field. I couldn't find a way. Basically, I couldn't write an update function parametrized by the field name. Is it possible at all? -- Feri.
