Suggestion to add clickable text activation function to Emacs

Emacs allows for the definition of buffer regions that represent "clickable
text", see "(elisp)Clickable Text".  One type of clickable text is a button
which can be programmatically activated (have its action executed) with the
push-button function.

But there does not seem to be a function to programmatically activate other
types of clickable text.  This is a suggestion that such a function be
added to Emacs.  It would be similar to push-button but would account for
all the ways clickable text can be activated.  Right now it appears that
non-button clickable text can be activated essentially only interactively,
e.g. with a press of RET or mouse-2 or invocation of their key bindings.
But that is only one of many possible ways of activating clickable text.

There is a function, mouse-on-link-p, that determines if the given position
is within clickable text, but there is no corresponding activation function.
