Re: Comparing a value to a list of numbers (in via smartmatch)

well, for completeness:

There is smartmatch ~~ (sometimes) acting like an in operator

  DB<24> $x=5

  DB<25> p $x ~~ [1,2,5,6,9,10,41..56]
1
  DB<26> $x=0

  DB<27> p $x ~~ [1,2,5,6,9,10,41..56]

  DB<28>

but

WARNING: Smartmatch is experimental

so you'd need to deactivate the warning and hope it'll never vanish (at your risk)

I personally would not use the smartmatch operator for anything. I did some experimenting with this experimental operator and found out that it is "too smart for me!". I could not accurately predict what this thing would actually do!	[reply]

I agree, but there is a real need for an "in"-operator like in other languages. I hope this aspect will survive somehow and I listed it for completeness with full warning. Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply]
