But if the above is more likely than 10% this means it will happen much
too often.  And i argued that learning Python in a PEP-308 world
might have this effect because nobody cares for and/or behaviour
and just uses the "well-known" ternary op. 

Just because *you* and all the others in the thread that another
idiom does not mean anything.  Many were looking for ternary-ops
and *then* came to and/or behaviour.  today.
