[issue19087] bytearray front-slicing not optimized

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

> A generic example is to parse messages out of a TCP stream. Basically
any protocol transported on TCP needs such a facility, or has to find
workarounds (which are either suboptimal or complicated).

Could you please show concrete code in which you are going to use this optimization?
