in reply to "map" sometimes uses only the last mapped value

It seems to have to do with returning a temp from inside a for loop. It's not just stringify, here: 
print map sub{return $_ for 0+shift}->($_), 1, 2, 3;  # 333
print map sub{return $_ for shift}->($_), 1, 2, 3;    # 123
print map sub{return 0+shift}->($_), 1, 2, 3;         # 123
print map sub{return 0+$_ for shift}->($_), 1, 2, 3;  # 123

Only the first of these cases messes up, funny
