Machine Type: x86_64-pc-linux-gnu
Bash Version: 5.0
Patch Level: 16
Release Status: release
Description:
Global and local variable namespaces are distinct in the most common case:
f() { local x=a; }
x=b
f
echo "$x" # still 'b', as expected
However, this^^^ example stops working when $x is declared read-only:
Repeat-By:
f() { local x=a; }
declare -r x
f # bash: local: x: readonly variable
This^^^ should not fail; it hinders reusability of shell functions and makes
them context-dependent.
