Integrate a wait/pause/delay in an #alias command chain

[buhtz]

I do create aliases like this

#alias{foo} {west;south;north}

How can I add delays into it?
Something like:

#alias{foo} {west;#wait{3seconds};south;north}

Tintin uses a slightly different approach:

#alias{foo} {west;#delay 3 {south;north}}
