Optional Result or _Result var for functions

A clear and concise description of what the problem is.

Many other languages have a feature where a function name is aliased to the variable 'RESULT'. This variable is a stand-in alias for the function name. It has the same type as the function and can be used instead of - or in addition to - the function's name as the target of an expression. It can also be used in place of the function's name so that it is clear - especially when the function has no arguments - that the function's result is being used in an expression, and it is not a recursive function call.

As people might use result for other purposes, the pseudo variable _Result could be used.

Describe the solution you'd like
IN some program there is
Dim Table$(100)
.
.
Now, is the following legal?

DefInt C
Function Check (X As String)
For Check = 1 to 100
if X=Table$(Check) then exit function
next
check=0
End function
' The function returns where X was found

This could be used instead:

DEFINT C
integer Function Check(X as string)
' In this case an implicit
'' DIM _Result as Integer
''is inside the function
For _Result = 1 to 100
if X=Table$(_Result) then exit function
next
_result=0 '(or)
Check=0
' Both do the same thing.
End function

Function xx$
result = " "
result = result + Table$(Check("Hello"))
exu

Of course these are contrived examples, but I think having either a variable called _Result (or Result) as a variable implicitly defined as local to that function that is an alias for the function's name would be a useful improvement to the language.

We have #212. This eventually turned into a similar discussion.
