Operators
The following table lists the precedence and associativity of all operators. Operators are listed top to bottom, in ascending precedence. Operators in the same cell have the same precedence. Operators are binary, unless the syntax is provided.

1
The exponent must be a compile-time constant of type u32
2
The right operand must be a compile time constant of type u32
3
If neither of the operands can be determined to be a compile-time constant, then we have a restriction: for the check a < b, if the field prime p is represented on N bits, |a - b| must fit in N - 2 bits.
Failing to respect this condition will lead to a runtime error.
