Another small V8.0 bug [message #71892]

I have found another bug in V8.0, at least for users who still have
round parenthesis used for indices lurking around in their code.
Like Mike Potter's example, it is not easily repeatable, and for
example sometimes only occurs after compile the program a second
time. And because it occurs in a fairly large program, I have not
yet isolated it into a simple test program. But I can illustrate
the problem after placing a STOP statement

% Stop encountered: SHOWDB 72 /home/landsman/uvot/bpm16274/
showdb.pro
IDL> help,list
LIST LONG = Array[1]
IDL> print,list[0]
183
IDL> print,list(0)
0
IDL> help,list(0)
<Expression> LIST <ID=22 NELEMENTS=1>
IDL> print,list(0) LE 0
% Unable to convert variable to type object reference.
% Execution halted at: SHOWDB 72 /home/landsman/uvot/
bpm16274/showdb.pro
% $MAIN$

IDL> print,!version
{ x86 linux unix linux 8.0 Jun 18 2010 32 64}

So IDL seems confused as to whether 'list' is a variable or an
object. (The code is all imperative statements with no object
syntax). Note that this differs from the long-standing variable/
function ambiguity that can occur when using the () syntax for
indexing. --Wayne
