Scala's tuple unwrapping nuance

Question

I\'ve noticed the following behavior in scala when trying to unwrap tuples into vals:

scala> val (A, B, C) = (1, 2, 3)
:5: error: not found: va         


        

Answer 1

From [scala] Question about naming conventions you can read

The initial capital letter has an advantage when pattern matching. Identifiers with an initial capital letter are considered to be values to match against instead of a variable to be bound.
