in template.html, modify 

TemplateInstance:
    TemplateIdentifier !( TemplateArgumentList )

to

TemplateInstance:
    TemplateIdentifier !( TemplateArgumentList )
    TemplateIdentifier ! Identifier
    TemplateIdentifier ! BuiltinBasicType
        TemplateIdentifier ! Literal

Literal:
    null
    true
    false
    __FILE__
    __LINE__
    NumericLiteral
    CharacterLiteral
    StringLiterals

but then in declarations.html you'd have to split up BasicType a bit.

And yes, this can't work for multiple parameters because the commas would cause
ambiguity with Expression. Same for identifier chains:

T!A.B == T!(A).B or T!(A.B) ?

and extended types:

T!i[] == T!(i)[] or T!(i[]) ?

etc.
