Lua.VM.RuntimeError exception (Lua v1.0.0-rc.0)

Raised by the Lua error() function.

Carries the original Lua error value, which may be any Lua type (string, number, table reference, etc.).

When raised without explicit :line / :source opts (e.g. from a stdlib bad-argument check), exception/1 populates them from the calling Lua source position via Lua.VM.Executor.current_position/0. That position is stashed in the process dictionary at every native-call boundary, so any raise site reachable from a Lua execution inherits the correct attribution automatically.
