Not exactly a one-liner, but pretty much a literal transcription using Xtreams:
| nesting |
nesting := 0.
('This is a (string) with some (parenthetical fields)' reading
transforming: [ :in :out || char |
char := in get.
char = $( ifTrue: [ nesting := nesting + 1 ].
char = $) ifTrue: [ nesting := nesting - 1 ].
out put: (nesting > 0 ifTrue: [ char asUppercase ] ifFalse: [ char ]) ]
) rest
