My newsreader seems to have quit putting >s in the margins. Sigh.

Harvey:
With some proposals put forward there is possibility for confusion if
colons, particularly as in else: are used as I can imagine it's not
always going to be clear whether a code fragment is part of an
if/elif/else statement construct or a conditional expression.

John:
The proposal on the table requires parenthesis around the entire figure:

(if <condition>: <expression> else: <expression)

There is no ambiguity.
