/**
* An abstract representation of a common expression.
* Expressions are abstractly represented as a collection of identifiers,
* select statements, function calls, literals, and comprehensions. All
* operators with the exception of the '.' operator are modelled as function
* calls. This makes it easy to represent new operators into the existing AST.
* All references within expressions must resolve to a [Decl][google.api.expr.v1beta1.Decl] provided at
* type-check for an expression to be valid. A reference may either be a bare
* identifier `name` or a qualified identifier `google.api.name`. References
* may either refer to a value or a function declaration.
* For example, the expression `google.api.name.startsWith('expr')` references
* the declaration `google.api.name` within a [Expr.Select][google.api.expr.v1beta1.Expr.Select] expression, and
* the function declaration `startsWith`.
