$json illegal in JSONiq

[Paul J. Lucas]

Given:

    jsoniq version "1.0";

    let $json := [ "\u0041" ]
    return <a>{ $json(1) }</a>

one gets:

</tmp/x.xq>:3,6: static error [err:XPST0003]: invalid expression: syntax error, unexpected "json"; raised at /Users/pjl/src/flwor/zorba/repo/bug-1200090/zorba/src/compiler/api/compiler_api.cpp:253

[Ghislain Fourny (gislenius)]

This is a known issue and is part of the bigger plan of bringing the Zorba parsers back in sync with the EBNFs from github.
