in reply to Unusual (and pointless?) idiom in old code

Is this in a loop, eliminating values from the previous iteration? If not, you don't need to assign anything at all. If it IS in a loop, try moving the declaration into the loop, so that once again you don't need to initialize, because limited scope causes the variable to be created, new and empty, once each time around.

I have similar problems, with code written 12 years ago by interns borrowed from the mainframe department and not supervised or peer-reviewed.

As Occam said: Entia non sunt multiplicanda praeter necessitatem.

[1nickt]: ugh, I stuck my head in the bass bin for 30 seconds on a dare at Ted Nugent at Hammersmith Odeon. Yes, I am 40% deaf now.
[johngg]: My daughter is incredibly jealous of my wife who got to see The Clash at Brixton many years ago. They went to see The Vaccines there recently.
[1nickt]: But the bands are even louder! I saw Spearhead (Michael Franti) at an outdoor show and had to walk a mile away to not feel pain in my chest! Babies were crying ... I asked the sound engineer why it was necessary to have the bass so loud and he laughed...
[Discipulus]: but the best i attended live was Mano Negra Patchanka at Forte Prenestino .. in 1990
[Corion]: Hmmm - Mano Negra or at least Manu Chao seem to put on a good live show. At least the one live CD I have from Manu Chao sounds good ;)
Discipulus feels the same jealousity of the johngg's daughter
[1nickt]: choroba I agree
[choroba]: Playing in a punk rock band for 20 years... my hearing is quite bad
[Corion]: I still have hopes to turn my godson and his two siblings into a punk band ;)
