I can make this work by changing parse.c line 3200. It surprises me that this
is in Parser::parseStatement; but since it's in the label "Ldeclaration", I
believe it is correct. It means that code like "nothrow int x=7;" is accepted,
but that's accepted at global scope already. So I don't think there's anything
wrong with this patch.


#if DMDV2
        case TOKimmutable:
        case TOKshared:
        case TOKnothrow:   // add this line
#endif
//      case TOKtypeof:
        Ldeclaration:

It needs a TOKpure added as well.

I'm not sure that you want to allow 'pure' on nested functions at all, because
of bug 2807. If it is allowed, a pure nested function needs to treat all of the
variables in the parent function as if they were globals.
