In 5.6 you'd do something like:

TEXT (area is [area])

and with the expression changes in RFC 64 this becomes:

TEXT ("area is" + [area])

For complicated uses this can be onerous. I propose adding attribute binding (e.g. straight substitution) for a string expression, e.g.:

TEXT "area is [area]"

This will make upgrading to 6.0 easier for folks. We'll still reserve the () syntax for true text expressions.

Added in 3cc3a1a (r11160). Note that with this change you can't do something like:

TEXT 'hello [world]'

where [world] is not a reference to an attribute. As a workaround one could do:

TEXT ("hello [" + "world]")
