I got in the habit of putting arithmetic operators at the start of a line while 
at university, having made too many errors from forgetting that the symbol at 
the end of the previous line was a minus sign. Of course, that consideration 
doesn't apply to commas, and it's amazing that Lamport (and Dijkstra?) managed 
to persuade people to adopt such crazy conventions.

Interactive theorem proving isn't the same thing as solving physics problems by 
hand, so I'm not against having operators at the end of the line if that's what 
people think would be best. Note however that the equals sign is an infix 
operator and is invariably put at the start of a line, never at the end.
