Identifiers
An identifier is a sequence of one or more alphanumeric characters and underscores that is used to name a language construct. The exceptions are:
-
A single underscore character does not form an identifier. Using a single underscore instead of an identifier means no identifier is given to this construct.
-
Cairo keywords cannot be used as identifiers.
|
Identifiers starting with an underscore are typically used to indicate an identifier that is intentionally unused, and will silence the unused warning. |
