feat: implement
with
statement (#197)
This expression would allow us to declare a local variable that will be used in remainder of a corresponding section. ``` condition: with foo = <expr>, bar = <expr> : ( <a boolean expression where you can use identifiers foo and bar> ) ``` Another advantage of this approach is that we can use it inside a loop. ``` for all offset in (10,20,30) : ( with val = uint8(offset) | uint8(offset + 4) | uint8(offset + 8) : ( val == 0x10000 or val == 0x20000 or val == 0x40000 ) ) ``` This implementation follows [RFC](VirusTotal/yara#1783) proposal.
