Initializing lexical-binding to t by default is currently not an option,
because it would introduce too much breakage.  For this reason, we need
to take smaller steps that will later make this change possible.

Because it will reduce the occurrence of the case where I copy a chunk
of code which relies on dynbind and then incorrectly execute it in
lexbind mode in `M-:` or ielm.
