Oh yes. The grammar is
http://dlang.org/template.html
TemplateInstance:
TemplateIdentifier TemplateArguments
TemplateArguments:
!( )
!( TemplateArgumentList )
! TemplateSingleArgument
TemplateIdentifier:
Identifier
And so
T!(3)!('b')
isn't parseable as a TemplateInstance.
As such, the compiler is behaving according to spec.
However, there's a problem: (T!(3)) is equally not an Identifier, so going by
this spec we can't even write (T!(3))!('b'). This seems overly restrictive.
But the error message is confusing, and liable to make the user think the
compiler is playing up. We should explicitly detect an attempt to do this, and
deliver a clearer error message. As such, I'm changing this to diagnostic.
