Re: [BUG] functions can't create global readonly variables
By the way it seems that, in bash at least, "readonly" breaks
encapsulation:
$ readonly foo=empty
$ fn() { local foo=bar; echo $foo; }
$ fn
bash: local: foo: readonly variable
empty
The only use I can see of this is for exported variables, where you
might want to ensure a specific value was always exported to an external
programme.
