Charm++ parallel programming system

[Robert Steinke <rsteinke AT uwyo.edu>]

In the user's guide it says:

The syntax of SDAG if statements matches that of C and C++. However, if 
one encounters a syntax error on correct-looking code in a loop or 
conditional statement, try assigning the condition expression to a 
boolean variable in a serial block preceding the statement and then 
testing that boolean's value. This can be necessary because of the 
complexity of parsing C++ code.

So inside of my SDAG code I sometimes have to do this:

serial
{
  sdagCondition = (some complex boolean expression);
}

if (sdagCondition)
{
  ...


The boolean variable sdagCondition can't be declared as a local in the 
serial block because it also needs to be visible inside the if. So I 
wind up adding it to my class as a member variable.  Could you 
automatically add a member variable for this purpose as part of the 
SDAG_CODE macro so that it doesn't clutter up my class definition? Maybe 
you could add the member variable and when parsing the .ci file always 
treat "if(X)" as if it were written:

serial
{
  sdagCondition = X;
}

if (sdagCondition)

Maybe that would allow it to correctly parse the C++ in more cases.
