If it's a feature, then it's definitely a new one since the original
specification of Objective-C. It turned out to be surprisingly hard
to find that specification, but I found a grammar description
here:http://www.cilinder.be/docs/next/NeXTStep/3.3/nd/Concepts/
ObjectiveC/B_Grammar/Grammar.htmld/index.html
There it says:
instance-method-definition:
<sp.gif><c2D.gif> [ method-type ] method-selector [ declaration-
list ] compound-statement
method-selector:
<sp.gif>unary-selector
<sp.gif>keyword-selector [ , ... ]
<sp.gif>keyword-selector [ , parameter-type-list ]
The declaration-list and compound-statement are not specified
further and are taken from the C spec. In other words: There's no
semicolon.
On the other hand, the grammar spec has been removed from Apple's
documentation, and I suppose the official line is now "Objective-C
is whatever we ship with Xcode."
I haven't booted my NS 0.8 cube in about a decade, but I'm pretty sure
the semi-colon was always required in the header file and always
allowed in the @implementation.
'Twas many a moon ago, but, I do distinctly remember triple-clicking
method declarations from headers (with semis) to copy-paste into my
implementation without deleting the semi. It always stuck with me as
an über-convenience.
