It is not possible to define a variable with the same name as the parameter

[lum7na]

I tried this code:

contract Test {
  function f(int b) private{
    uint b = 0;
  }
}

I expected to see this happen: The variable b defined inside the function body should be able to override the function parameter name, similar to the behavior in solc.

Instead, this happened: Solar threw an error message: error: identifier b already declared.

I think you mean "It is not possible to define a variable with the same name as the parameter"

It is arguable that permitting the shadowing of variables is within spec even though the compiler raising a warning and is discouraged

Warning (2519): This declaration shadows an existing declaration.
