pretty: string_expr now has a precedence model, so it displays parentheses where necessary (presently, if a field-replace appears in the position of a 'primary').

parsem: Now parses field_replace expressions (added expr_prime).

1102. By Matt Giuca on 2010-06-18

parsem: Added extra production for 'primary'. Currently, expr just calls primary, but soon fieldreplace will be an expr, but not a primary (see doc/ref/exprs).

Added new expression type 'fieldreplace'.
Typechecks (currently just error), converts to CFG, and pretty-prints. No parser yet.

doc/ref/expr: Fixed ambiguity in grammar relating to the new field_replace expression. Formally defined ':=' operator as right-associative and with the lowest precedence of all expressions.

doc: Added field replace expression documentation.

1098. By Matt Giuca on 2010-06-18

Completely removed fieldreplace statement (supposed to be an expr, not a stmt). It was unused anyway (as the type checker rejected it), so this doesn't cause any distruption.

pretty: Fixed printing of fieldset, to the new '=!' syntax.

1096. By Matt Giuca on 2010-06-18

ir: Remove references to 'Venus' and comments that certain things are 'Mars only'. There is no Venus, only Mars.

1095. By Matt Giuca on 2010-06-18

Changed syntax for fieldset from 'e.f = v' to 'e.f =! v'. This gives it the scary syntax it deserves, being an impure update operation. (LP: #595782)
