- Here is a part of a procedure's disassembly.
- The procedure appends an [unset b] to some other value.
- (76) unsetScalar 1 %v2 # var "b"
- (82) push1 1 # ""
- (84) strcat 2
- bug? feature? optimized elsewhere?
- ...it even knows unset's result is empty...

In light of my newer paste (performance drop with empty string concatenation), the disassembly looks the same in 8.6.5 and trunk version.
