arrow function in a qml file
SUMMARY
***
When parsing qml files the parser throws unexpected token on arrow functions
and template literals/strings then will stop updating after changes are made
both of these are well supported in javascript for a long time
***
STEPS TO REPRODUCE
1. Open a qml file with an arrow function or template literals
(https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals)
2. wait for parser to finish
3. Unexpected token `>' will appear next to arrow functions
Unexpected token `' will appear next to template literals
4. Hover functions; the "where is this declared" box doesn't work for the file,
neither does highlighting
5. Parser will sometimes stop working kdevelop is restarted
OBSERVED RESULT
arrow functions and template string will show as errors and highlighting will
fail
EXPECTED RESULT
file parses normally, and is fully highlighted
