Block expressions #8

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I would like to see blocks allowed in the expression language. We should be 
able to introduce variables, either through compound-statements like 
JavaScript, or let-clauses like Haskell.

One workaround for temporary variables is to use logic variables. These are 
variables output by a single method in a single constraint, much like output or 
invariant variables. The semantics of placing them in a logic section is that 
they represent a subexpression.

However, this will not work for subexpressions involved in a self-loop, as it 
will turn the self-loop into a multi-constraint loop, prohibiting solution of 
the system.

Now that we've switched to The JavaScript Way, this is no longer a priority.
