Comment(by ehuelsmann):

 Problem is that we have DEFSTRUCTs in our code; we can't just reject
 redefinition, because that'd negatively interact with our current
 bootstrapping procedure.

 Analysis of other implementations:
 1. SBCL offers a restart Continue/recklessly-continue/Abort
 2. clisp just continues

 The solution we want to see implemented is: detect differences in
 definition and offer a restart to continue (change it).

 This doesn't affect our bootstrapping since we always define to the same
 definition.
