-Just like for L, the type of localization is determined from which kind of reference C<$value> is when C<$what> is a glob, and from the sigil when it's a string.
+Unlike L, C<$what> must be a string and the type of localization is inferred from its sigil.
+The two only valid types are array and hash ; for anything besides those, L will throw an exception.
C<$key> is either an array index or a hash key, depending of which kind of variable you localize.
If C<$what> is a string pointing to an undeclared variable, the variable will be vivified as soon as the localization occurs and emptied when it ends, although it will still exist in its glob.
