Hi,

as you probably saw, I pushed my first significant changes to the Compiler 
package. I hope the compiler experts will take a look at them. While I was 
changing stuff, I found that some methods of Scanner are unused:

#errorMultibyteCharacter
#nextLiteral
#checkpoint
#revertToCheckpoint:

They seem to be rather old (~10 years) and I don't think any external code 
use them. Should we deprecate or just delete them?


Cheers,
Levente
