That is the primary purpose.  For most datasets str_replace('  ', "\t",
var_export($obj, true)) gets what I want.  But this is for exploration of
process. I don't expect it to be committed to the language on a permanent
basis. To be honest, it would be better as a php.ini setting -
export_indentation.  The default value would be '  ' and PHP would fall to
that value if it isn't set.

And I'll likely do that as a step two learning thing.

Changing how includes work was my first suggestion and what I'd like to wor=
k
on, but that has to come after more elementary things.
