[Haskell-cafe] Named field syntax

[Maurí­cio]

Hi,

I see that this works:

data Test = Test Integer String

This also works:

data Test = Test {a::Integer,b::String}

However, this doesn't:

data Test = Test Integer {b::String}

Is there some way to name only a single, or a few,
of some data type fields?

Thanks,
Maurício
