in reply to Index number repeating in for loop

Two quick solutions, one the same as AnomalousMonk's but I'd already run it so I might as well post it!

$ perl -Mstrict -Mwarnings -E ' my $want = q{F}; my @text = q{A} .. q{J}; for my $index ( 0 .. $#text ) { next unless $text[ $index ] eq $want; say qq{$want at $index}; last; } my $index; for my $elem ( @text ) { do { $index ++; next; } unless $elem eq $want; say qq{$want at $index}; last; }' F at 5 F at 5 $

Cheers,

JohnGG

[Corion]: Whee! Germanys Grand Central Airport (for Berlin, re-scheduled for the thrid or fourth time, to open now in 2018) has just fired their technical lead
[ambrus]: Corion: Is their budget estimate four times the initial estimate yet? Was the construction late by six months already three months after they started?
[marto]: I'll believe it when I see it. That's been due for many years now :P
[marto]: oddly the last time I was there I saw a zeppelin in flight for the first time
[Corion]: ambrus: I don't know how far the budget estimate has been overrun yet
[Corion]: marto: Heh ;) No, you were likely at Tegel or Schönefeld, the new one ("BER") will be somewhat outside of Berlin ;)
[marto]: Corion Schoenfeld, but my friend has been telling me about this new airport for about 7-8 years now :P
[marto]: I doubt it even exists as a building site :P
