So I have no idea how this really works, of course, but does this
mean that the `text` pattern cannot contain pipe symbols? I.e. that
you cannot use pipes in the test template?
Hmm. I didn't try. I hope lark is smart enough to keep pipes that are
out of {} [] as is.. But of course, you can't hope that pipe inside {}
or [] will work as bash-pipe.
Yep, sure. It’s just that the `text` nonterminal symbol doesn’t look
like it could match anything with a pipe in it.
Same thing with other special symbols ("{}" and "[]"). I don't want to
care about this too much now. This simple grammar works good for test
template in patch 03. If we need something more, we can add a kind of
special symbols escaping later.
But yes, if someone trips over this (i.e. we ourselves), we can still
fix it then.
