If you writing your own cache basing on includes, you can write sequence 
that handles deletion correctly, knows if your own data exist or not and 
doesn't need include path functions for that.

More functionality requires more code. I think it's better than turning 
the language into kitchen sink of similar language constructs, each has 
a little tweak to suit one particular use case. Next thing we would have 
framework_include, database_include, template_system_include, 
my_personal_homepage_include and so on. I think we need to do very 
generic stuff in the language, less generic in functions and yet less 
generic - in user code.

We could also have function file_find() (or any other name, let the 
bikeshedding begin) or something that would resolve filename against 
include path and return full name if such exists or false if none 
exists. That seems generic enough operation to have a function for.
