new function for <?php print base_path() . path_to_theme() ?>

@momper, Thank you for the idea!

There hasn't been any discussion here in 11 years to further support this addition. So, this proposal doesn't met the Criteria for evaluating proposed changes → . In this case, there is not demonstrated demand and support for the change.

Therefor, I am closing this issue.
