At least one valid technical argument was raised -- invariant already has a 
different meaning in D1.

The other argument I remember is that you basically have to use immutable to 
describe what invariant means ;)

And I think the concept of templates was more difficult for me to get than 
the syntax.

The syntax ambiguities are somewhat of an orthoganal issue that was solved 
by using !() instead.

In other words, I don't think using ! without parens is going to make 
templates any easier to understand for newbs.  It might not make it more 
difficult, but in my view, it's a very trivial change.
