Detailed Description

A trivial emitter that outputs syntax straight to the stream.

This emitter does neither pretty printing nor XML markup. It dumps any tokens straight to the final output stream. It can be used as the low-level back-end for EmitPrettyPrint.

	)

inlinevirtual

Emit a variable token.
