RETURN always evaluates the expression that follows:

RETURN m.x + m.y

is no different than

RETURN (m.x + m.y)

As Mike said, the only time parentheses change what happens is when VFP expects a name. Then, the contents of the parentheses are treated as a name:

USE Table

tries to open a table named Table.

USE (Table)

tries to open a table whose name is contained in Table.
