Tag {if $value in $array} ParseError syntax error, unexpected identifier “in”

Hello,

I have seen somewhere on github this interesting latte tag {if $value in $array}:

{var $inputClass = $input::class}

{if $inputClass in ['Nette\Forms\Controls\SubmitButton', ....]}   // this only one syntax works
    .......
{/if}

The code sample above works well, although I have not found this tag {if $value in $array} in the official Latte documentation. But only some of syntax cases works, many dont – see samples:

{var $inputClass = $input::class}

{var $buttonClasses = ['Nette\Forms\Controls\SubmitButton', ....]}

{if $inputClass in $buttonClasses}       // ParseError
    .......
{/if}

{if $input::class in ['Nette\Forms\Controls\SubmitButton', ....]}  // ParseError too
    .......
{/if}

The syntax “if in” is cool and I like it, but the support for that syntax is weak.

My question is – is this syntax an latte official one, or not?

I propose to complete the support and add into the documentation.

Thanks
