I think functions side step some problems aliases have.  I seem to
remember aliases not living thru some situations where functions are
still available.  But didn't try to reproduce.

You may have hit a problem I hit long ago when I started using bash
functions. 

syntax should be:

  name () { some.cmd; }

All ingredients are important... The space after and before {}
The semi-colon after `some.cmd'

They can be fairly elaborate if you watch the syntax.  Here is my most
elaborate one in current use:

enlp () { if [ -z "$1" -o "$1" = help ];then
              echo "Usage: \`enlp [args]  FNAME'"
              echo "Current args are:"
              echo "   enscript -f AvantGarde-Book10/12 -F Times-Roman 14/16 \\"
              echo "    --margins=60::: --word-wrap -G "
          else
enscript -f AvantGarde-Book10/12 -F Times-Roman 14/16 --margins=60::: --word-wra
p -G "$@"
       enscript -f AvantGarde-Book10/12 -F Times-Roman 14/16 --word-wrap $1
          fi; }

Functions can be sourced same as other env stuff.
