Example
myfunc(){
echo "I will never be executed."
}
another_func(){
# this "redeclare" overwrites original function
myfunc(){ echo "I am the one and only"; }
}
# myfunc will print "I will never be executed"
myfunc
# but if we call another_func first
another_func
# it gets overwritten and
myfunc
# no prints "I am the one and only"
The latest declaration wins. There are no such things as namespaces! However, functions can contain other functions.
