Alias expansion happens when a command is read, not when it is
executed.  So in this case, it happens when the function is defined,
which means you would need to define the alias and have expand_aliases
turned on before the function definition:

alias ls='ls -l'
shopt -s expand_aliases
function foo
{
ls /
}
