Note the returned boolean value "safe" is set either to true, if there is only one possible language detected or, to false otherwise.
To get a list of possible languages for a given file, you can use the plural version of the detecting functions.
```go
langs := enry.GetLanguages("foo.h", "<cpp-code>")
// result: []string{"C++", "C"}
langs := enry.GetLanguagesByExtension("foo.asc", "<content>", nil)
// result: []string{"AGS Script", "AsciiDoc", "Public Key"}
langs := enry.GetLanguagesByFilename("Gemfile", "<content>", []string{})
// result: []string{"Ruby"}
```
