Summary:                    Ugly error message if incorrect default value for
parameter
Description: 
module Program
{
  Test(_ = false : bool) : void // E: invalid default value for parameter
'_N_u1583': '(false : bool)', only literals are supported
  {
  }
  
  Main() : void { }
}

The 'invalid default value' is ugly. Compiler must say:
Incorrect format of parameter default value. You should use 'paramName =
<literal> : <type>'.

I suggest inferring type instead of error in that case.
After all just (_ = false) compiles.
Also it'll allow to write (_ = 1u)
