tmp=0; tmp+1:(tmp+=5)

[Etienne Grossmann]

  Hello,

  I would like to know whether the in a range "a:b", the left operand
is always evaluated before the second. That is, can I do :

  tmp=0; tmp+1:(tmp+=5)

  and expect to get 1:5. I didn't find where in the docs the order of
evaluation is specified.

  With 2.1.34, this works. Is it an undocumented feature? Can I expect
it to work w/ future versions?

  Cheers,

  Etienne
