If you don't want to write code to any output file,
just use a tangler with a null sink device. That device
just throws away all the data written to it.
For example:
Start C section to null sink[1]
1: #line 128 "iscrqa.ipk"
2: @from interscript.tanglers.c import c_tangler
3: @from interscript.drivers.sinks.null import null_sink
4: @dummy = c_tangler(null_sink(), weaver)
5: @select(dummy)
6: /* These comments do not get written out */
