Liquid if variable starting with 'empty' creates exception

{% if emptyCard %}
<p>Creates Invalid 'if' tag exception in 1.2, worked fine in 1.1</p>
{% endif %}

{% if cardEmpty %}
<p>Works fine</p>
{% endif %}

Not sure if this is an issue. Did emptyCard get assigned anything?
And here what is the difference with cardEmpty? We don't see it getting assigned any value either.

Probably a bug in the parser because it reads empty which is a keyword and gets confused. In the meantime please don't start your identifiers with empty.

Ah, I see now, the emptyCard has a string value of 'empty' which doesn't parse correctly. Thanks @sebastienros
