Minor Parsing issue with data-link

[BrentH-Alnico]

Hi Boris,

I have a case where I tried doing this...
data-link="disabled{:~inObjectArray(array, {'key1': val1, 'key2': val2})}"
...which resulted in a syntax error likely due to inner curly braces.

However, this method works; but of course cannot be used on two-way data-bound tags.
disabled="{{:~inObjectArray(array, {'key1': val1, 'key2': val2})}}"

One work-around
data-link="disabled{:~inObjectArray(array, 'key1', val1, 'key2', val2)}"

inObjectArray: function(array, key1, val1, key2, val2) {
    return array.some(obj => obj[key1] == val1 && obj[key2] == val2);
}

Here is a test file: https://jsfiddle.net/alnico/e8pgm3k0/

I know the parsing code is quite complex, hopefully this is fixable, but if not, no big deal.
