Query a value in a tuple, within a list of tuples

[Madd0g]

I'm experimenting with different features, I wanted to see if I could make it work and I couldn't

:create table {
  id: String,
  => 
  meta: [(String, String)],
}

?[id, tuple] <- [['a', [['hello' , 'world']]], ['b', [['variable' , 'alive'], ['age' , 'old']]]]

:put table { id => tuple }

I wanted to be able to get the record if the value next to hello, variable or age matches some value (like hello=world).

I tried to do something like in the docs - how to join relations with a first layer and then a second layer. I tried using first() but couldn't make sense of the logic.
