Michael Neale commented on JBRULES-269:
---------------------------------------

ha ! yes I like python, as long as we don't start requiring indentation ;)

we may have some other ways to avoid so many keyword collisions (using semantic predicates for working out keywords rather then hard coded tokens for the lexer).

> Given that we are not going down the route of 
> when {
> }
> style brackets, we will need to be stricter about newlines. 
> In otherwords, newlines are required I believe in the following scenarious:
> before a when, 
> after a when before the LHS
> before a then
> after a then before then RHS
> before an end (at the end of the rule).
> when,then, end - should all appear on a line by themselves.
> Optionally (perhaps?) rule should always be at the start of a newline.
> on a similar note, should rule and end be at the start of a newline? (don't really want to have to enforce column positions - but it is kind of needed).
