(aside: tip^3 doesn't make sense - a changeset can have at most 2 parents)

I'm not sure I understand what you mean by safe. That wouldn't work in bash:

  $: hg log -r parents(tip)
  -bash: syntax error near unexpected token `('

It's also much longer to type than just putting quotes around the caret version:

  hg log -r "tip^2"
