Calls to `show` have been removed. To counter the loss of information,
the error positions have been improved and now correctly point to the
current selector instead of the entire select expression.

When an attribute selection fails, the error message now correctly points to the attribute in the chain that failed instead of at the beginning of the entire chain.

Failed asserts don't print the failed assertion expression anymore in the error message. That code was buggy and the information was redundant anyways, given that the error position already more accurately shows what exactly failed.
