The left argument to any evaluator (•BQN, •Eval, •ScopedEval, result of •MakeREPL), if given, is a list of up to three elements, giving a prefix of •state (see next section) during evaluations of that function. Thus ⟨"","xyz"⟩•BQN"•name" returns "xyz".

The effect of •Eval should be the same as if its argument were written as source code in the scope where •Eval appears. It can define variables, and modify those in the current scope or a parent.

•ScopedEval creates as new scope for evaluation as it is loaded. Other than its syntactic role, it is effectively equivalent to {•Eval}. Parent scopes are visible from the created scope; to make a scope without this property use •BQN"•Eval" or •BQN"•ScopedEval".
