Herman,
I think you're misunderstanding my point. The "(" and ")" aren't the
issue. My point is that LC won't accept any type of expression (other than
a variable name) with or without parentheses as a custom property name.
The first and third examples you gave above should work, with or without
the parentheses. The presence of "set" and "of" tell the compiler that a
custom property is being referenced and, although I'm certainly not an
expert on parsing, I can't see why the compiler ( or the engine at runtime)
can't evaluate an expression which results in a custom property name before
executing the rest of the command. That's what happens everywhere else in
LC although sometimes the value() function is required.
