Loading real yaml fixtures containing markdown links fails

[c33s]

App\Entity\Item:
    item_1
        __construct:
            visible: true
            rank: 50
            text: >
                example text
                more text [markdown link with reference][1]
                
                [1]: https://github.com/nelmio/alice/issues/new

leads to UnresolvableValueExceptionFactory

it's an escaping problem.

changing all to

App\Entity\Item:
    item_1
        __construct:
            visible: true
            rank: 50
            text: >
                example text
                more text \[markdown link with reference\]\[1\]
                
                \[1\]: https://github.com/nelmio/alice/issues/new

think the following issue would be the best location where a solution could be found #840

@c33s just thought of it but maybe there is a simple solution: add a new delimiter:

App\Entity\Item:
    item_1
        __construct:
            visible: true
            rank: 50
            text: >
                ALICE_ESCAPE # will escape all that follows
                example text
                more text \[markdown link with reference\]\[1\]
                
                \[1\]: https://github.com/nelmio/alice/issues/new
            anotherText: >
                ALICE_ESCAPE_START # will escape all that follows
                example text
                more text \[markdown link with reference\]\[1\]
                
                \[1\]: https://github.com/nelmio/alice/issues/new
                ALICE_ESCAPE_END # everything after is not escaped hence the following current will be evaluated
                <current()>

And in the expression language we add a new token/parser that takes precedence or something. I say "simple" in that it looks simple but I don't know how feasible that actually is. I have a brief memory of having looked at it once but I don't remember if I stopped by lack of time or because I hit a wall
