Assign to t the value of the string s, with all letters mapped to their lower case.
t = s.toLowerCase();
var t = s.ToLower();
import "strings"
t := strings.ToLower(s)
let t = s.toLowerCase();
local t = string.lower(s)
t := LowerCase(s);
$t = lc $s;
t = s.lower()
t = s.downcase
let t = s.to_lowercase()
