question about "Flexible Inheritance for Class Functions", BB manual

[Robert P. J. Day]

  was thinking of tweaking some of this part of the manual, first a
couple questions.

  in that section:

file:///home/rpjday/oe/dist/layers/bitbake/doc/_build/html/bitbake-user-manual/bitbake-user-manual-metadata.html#flexible-inheritance-for-class-functions

the intro correctly explains how one can normally make adjustments to
an inherited task from a class file, i just want to have a complete
list as to the possibilities:

 * do nothing and accept the inherited task as is
 * _append or _prepend (or possibly both) to the task
 * override it completely by redefining the task

i would also have added:

 * delete the task with "deltask"
 * delete the task with var flag "noexec"

first question -- is that pretty much the complete set of what one can
do with regards to an inherited task? am i missing anything obvious?
and the only drawback to providing that list is that deltask and var
flags are explained in subsequent sections so the ordering would be a
bit off.

  also, even if one uses the EXPORT_FUNCTIONS feature, i'm assuming
one can ignore that and still use all of the above unchanged, yes?

  still pondering as to how i'd rewrite this for clarity.
