In other languages you can freely introduce local scopes { ... }, this
isn't possible in Bash since a local corresponds to a function; but
it's not really that hard to replicate, now consider this instead:
test()
{
local test="FUNCTION"
echo ${test}
x(){
local test="LOCAL SCOPE 1"
echo ${test}
};x
echo ${test}
x(){
local test="LOCAL SCOPE 2"
echo ${test}
};x
echo ${test}
}
test
Now 'x' is vague, you could replace 'x' by a name documenting the scope.
I consider this to be more clean than using a variable to remember it,
especially when multiple local scopes are to be used after each other.
