/// @assertion StackTrace current
/// Returns a representation of the current stack trace.

/// This is similar to what can be achieved by doing:
///
/// try { throw 0; } catch (_, stack) { return stack; }
/// The getter achieves this without throwing, except on platforms that have no
/// other way to get a stack trace.
/// @description Checks that this property can be called and contains not null
/// value
