commit 42024539877fbebfdfbbc9b006106454cdaf5187
Author: Jonathan Worthington <jnthn@jnthn.net>
Date:   Thu Nov 1 18:00:04 2018 +0100

    Do a lot less work upon a redeclaration
    
    The variable is already there, so we don't need to go and do all of
    the things we would were it not. This also avoids scribbling over the
    things the optimizer uses to tell the difference between a parameter
    or declared variable, fixing an issue introduced by the lexical to
    local lowering.
