You're not learning from the mistakes of other languages (ruby in this case, 
which removed Enumerable from String in 1.9) ... "foreach" makes no sense for 
strings, because it's unclear what you want (with unicode terminology here, 
as this is for php6): 
"for each byte" "for each codeunit" "for each codepoint", or "for each line", 
or ... if you want to use foreach in your example, just do 
foreach (str_split($str) as $value) { ...
