Bug description: Needs explicit statement on falling off the end of a function
Description:
------------
There is no official statement of the meaning of exiting a function other
than through a 'return' statement. Specifically, it is possible to execute
to the end of the function, but then what is the value of that invocation?
Reproduce code:
---------------
---
From manual page: language.functions
---
Not in "returning values" or "return()" either. "Returning values" is
probably the best place for it.
Expected result:
----------------
Since many other languages will use the value of the last expression
evaluated as the return value of a function which does not explicitly
'return', it would be helpful to note prominently that PHP (apparently)
does not do this. It seems that the value of an invocation of such a
function is NULL.
