  Log:
  Bind implicit parameters via "let"s, deprecating the "with" and "dlet"
  binding forms.
  
  * A "let" may now contain either a list of implicit parameter bindings,
    or a list of 'normal' ones, BUT not a mixture.
  * To avoid unecessarily upsetting existing i-param code, the 'W' toggle
    enables support for the old "with" and "dlet" binding forms. With time,
    this backwards-compatibility toggle will be dropped.
  * Note: only expression-level "let"s may be used to bind implicit parameters,
    i.e., binding them via comprehension/do-level "let"s (and "where", for that matter)
    is not currently supported.
  
    [ My understanding (which is limited) is that the meaning of allowing
      i-parameter bindings in those contexts is unclear.
    ]
  
  * The wording of the error messages has room for improvements.
