Issues Reading Arrow Functions

[luisaugusto]

When I use a filter in a Twig template, such as:

{{ [1,2,3]|filter(x => x == 1) }}

I get the following error:

Error: ERROR: Unexpected token "operator" of value ">"

> 22 | {{ [1,2,3]|filter(x => x == 1) }}
     |                      ^

What should happen is that the Twig parsing should recognize an arrow function and be able to format the file correctly.

Bump. Same for map. All arrow functions are not working.

@luisaugusto , maybe rename the issue to problems with arrow functions.
