Thanks a thousand Daniel!!! Finally! there is someone who really read my
post and try to understand it before jumping to conclusions.

Sorry if I was not clear in my OP, to all those people who were trying to
understand what I was saying. 

I have the following alias and function *already* defined in my ~/.bashrc:

  $ bash 

  $ alias rd
  alias rd='rmdir'

  $ type dt
  dt is a function
  dt () 
  { 
      pushd +$1
  }

  $ exit
  exit

I.e., there are there in the interactive shell. Now I want to use them in
my script:

  $ bash -O expand_aliases -c '. ~/.bashrc; (rd /tmp/ttt; alias rd; dt 3; type dt)'
  bash: line 0: alias: rd: not found
  bash: dt: command not found
  bash: line 0: type: dt: not found

I.e., even sourcing .bashrc won't work.
