My bad. I wanted to write:

 print('(a)'), 'Hello'

which is valid code and accepted. (Cf. PR33269 for detecting this.)

> read ('(f3.3)'), a ! Invalid, rejected at compile time, requires unit number.

I disagree - and also NAG f95 agrees with me; READ has two form:

R910 read-stmt is READ ( io-control-spec-list ) [ input-item-list ]
               or READ format [ , input-item-list ]

And I would argue that "read '(f3.3)', a" and "read ('(f3.3)'), a" are both of
the second type. As both are default-character-expressions, this should be
valid. As is my - fixed - PRINT case.
