// Protos returns a cel.EnvOption to configure extended macros and functions for
// proto manipulation.
//
// Note, all macros use the 'proto' namespace; however, at the time of macro
// expansion the namespace looks just like any other identifier. If you are
// currently using a variable named 'proto', the macro will likely work just as
// intended; however, there is some chance for collision.
//
// # Protos.GetExt
//
// Macro which generates a select expression that retrieves an extension field
// from the input proto2 syntax message. If the field is not set, the default
// value forthe extension field is returned according to safe-traversal semantics.
//
//	proto.getExt(<msg>, <fully.qualified.extension.name>) -> <field-type>
//
// Examples:
//
//	proto.getExt(msg, google.expr.proto2.test.int32_ext) // returns int value
//
// # Protos.HasExt
//
// Macro which generates a test-only select expression that determines whether
// an extension field is set on a proto2 syntax message.
//
//	proto.hasExt(<msg>, <fully.qualified.extension.name>) -> <bool>
//
// Examples:
//
//	proto.hasExt(msg, google.expr.proto2.test.int32_ext) // returns true || false
