A declaration statement has one of the forms
CONSTANT c1,...,cn VARIABLE v1,...,vn
where each vi is an identifier and each ci is either an identifier or has the form Op(, ... ,
), for some identifier Op.
Perhaps Leslie can shed some light on why that decision was made.
But this only applies to constant parameters, you can of course *define* higher-order operators.

Hi,
I'm trying the following:
```
CONSTANTS X(_, _)
LOCAL Err == X(1, LAMBDA y: y)
```
This introduces a parsing error at LAMBDA. If I change X to
CONSTANTS X(_, F(_))
then the parsing error is at F.
How do I define a higher-order constant operator?
Thanks!
