Per bash manual:
-----8<-----
ALIASES
...
Aliases  are  expanded when a function definition is read, not when the
function is executed, because a function definition is itself a command. As a
consequence, aliases defined in a function are not available until after that
function is executed. To be safe, always put alias definitions on a separate
line, and do not use alias in compound commands.
