 * *`json $value`*: Returns the JSON representation of `$value` as a `string`.
 * *`keys $map`*: Returns the keys from `$map`. If `$map` is `nil`, a `nil` is returned. If `$map` is not a `map`, an error will be thrown.
 * *`last $array`*: Returns the last value of an array.
+* *`parseBool $string`*: parseBool returns the boolean value represented by the string. It accepts 1, t, T, TRUE, true, True, 0, f, F, FALSE, false, False. Any other value returns an error. Alias for [`strconv.ParseBool`](http://golang.org/pkg/strconv/#ParseBool) 
 * *`replace $string $old $new $count`*: Replaces up to `$count` occurences of `$old` with `$new` in `$string`. Alias for [`strings.Replace`](http://golang.org/pkg/strings/#Replace)
 * *`sha1 $string`*: Returns the hexadecimal representation of the SHA1 hash of `$string`.
 * *`split $string $sep`*: Splits `$string` into a slice of substrings delimited by `$sep`. Alias for [`strings.Split`](http://golang.org/pkg/strings/#Split)
