Actually, that doesn't matter at this point -- in the context of "an
expression", the curly-braces are NOT needed to resolve the value of a
STREAMX variable.  In other words, you need something like this:

::assign flag "Y"
::if flag="Y"
::   echo flag is !flag
::   echo flag is {flag} is another way of saying the same thing
!comment at submission time, flag was set to "{flag}"
::endif

The key is deciding what an "expression" is -- there are three possibilities

   if <expression>

   echo ![<expression>]

[and for streamx in particular]

   !comment an actual jobstream line with an {<expression>}
