[antlr-interest] Concatenating child nodes into one

[Elnur Cabarov]

This method doesn't work for me. I have to use rewrite rules, not tree
operators, because I insert imaginary nodes.
Being precise I need this

importDeclaration

    :   'import' 'static'? qualifiedName ('.' '*')? ';' -> ^(REF
IMPORTS qualifiedName)
    ;

And when I change literals to lexer rules I get:
The following token definitions can never be matched because prior tokens
match the same input: IMPORT,STATIC

Thank you
