+# Introduction
+
+Programmers from languages like Java or C++ may miss an `enum` type, providing type-safe constants.
+
+# Code
+
+ type LogLevel struct { name string }
+ var (
+ LL_FATAL = LogLevel{"fatal"}
+ LL_ERROR = LogLevel{"error"}
+ LL_WARN = LogLevel{"warn"}
+ LL_INFO = LogLevel{"info"}
+ LL_DEBUG = LogLevel{"debug"}
+ )
+
+This code allows functions to take a parameter of type `LogLevel` and prevents callers from accidentally passing values of other types for this parameter.
