Bug #5235: Ruby fails to freeze Strings and Numerics.

x = 0
x.freeze()
x += 1
x # => 1

s = ""
s.freeze()
s += "a"
s # => "a"

[aprescott (Adam Prescott)]

This is not a bug. x += 1 is sugar for x = x + 1, and x + 1 does not
modify the receiver. Similar for s += "a".

s = ""
s.freeze
s.replace("nothing") #=> RuntimeError: can't modify frozen string

• Status changed from Open to Rejected

#freeze prohibits modification to an object, not a variable.
