Hello, everybody.

I've just committed a provisional fix to this bug in branch
feature/positioned-lambdas.
On starting Emacs and doing C-h v org-mode-hook RET, the following gets
displayed:
org-mode-hook is a variable defined in `org.el'.
Its value is shown below.
Not documented as a variable.
This variable may be risky if used as a file-local variable.
You can customize this variable.
Value:
({org-ctags.el 7605} #f(compiled-function () #<bytecode -0x15a0204bcec6752e>)
{org-mouse.el 30108}
#f(compiled-function () #<bytecode 0x1c77f77cde0ab8f0>) {org.el
844741} #f(compiled-function () #<bytecode -0x2a221d361c9ad4a>)
{ob-core.el 59418}
#f(compiled-function () #<bytecode -0xa13ed1a788fcde6>)
org-babel-result-hide-spec org-babel-hide-all-hashes)
Original value was nil
.. Each anonymous function is annotated with a buffer name and offset
which indicates the position of the source of the function.
Clearly there is room for improvement: The display is not well filled; a
file name may be better than a buffer name; line/column numbers may be
better than buffer offsets. There is also a possibility for putting
buttons on the text fields to bring up the source code.
