Method C<absolute> runs C<IO.resolve> on paths to produce absolute paths
after expanding leading C<~/> to C<$*HOME>.


Rakudo considers paths starting with a C<~/> to be relative paths:


'~'.IO.is-relative.so       # True
'~/'.IO.is-relative.so      # True
'~/hello'.IO.is-relative.so # True


This method expands the leading C<~/> to C<$*HOME>. Thus, it does not
consider paths beginning with C<~/> to be relative paths.


Method C<relative> resolves a path (C<$path>) relative to the base
directory of a file (C<$base>).


This method is intended for config files which allow users to specify
relative paths. When relative paths are given in a config file, these
relative paths should be resolved I<relative to the config file's base
directory> for DWIM.


Like method C<absolute>, method C<relative> expands leading C<~/>s to
C<$*HOME>. Thus, it does not consider paths beginning with C<~/> to be
relative paths.
