If you are constructing a new object then you don't need to limit yourself
to a single one. You could use A for absolute paths and R for relative
paths:

  R/'relative'/'path'
  A/'absolute'/'path'

Or even P.absolute and P.relative:

  P.relative/'relative'/'path'
  P.absolute/'absolute'/'path'

And you could even go as far as make one the default and the other not to
promote one over the other:

  P.relative/'relative'/'path'
  P/'absolute'/'path'
