Type of parameter to Lambda

[Emanuel_Swe]

Hello. I wonder if there is a special reason for writing the type

Code: Select all

(Data x) ->

in the lambda expression. You wrote that the expression in first option was syntactically correct.

As the explanation says, the variable name in the lambda cannot be d because d is already used in the method. That is why even though syntax of the lamda in option 1 is correct but it will not compile. Data x doesn't have that problem.

Thank you, I just wonder why it says "(Data x)->" and not just "(x)->"

There is no special reason for that.
