It's even stranger because on the command line, these examples are
(rightly) rejected. In the notebook as well as in a loaded ".sage"
file I am observing this worrying behaviour as well. Especially the
parsing of "1=5" makes me seriously want to turn off "implicit
symbolic function definitions", if only that wouldn't prevent me from
saving 2 painful quotes by using
_(x,y,z)=1
instead of
var("x,y,z")
