Re: Re: Some suggestions on coding style

You're right! I looked at this post and they mentioned using single quotes when no interpolation of variables is needed. They also mentioned that this is a matter of personal preference. This probably would be good practice, but in my use, I'm not sure if it makes that big a difference. I wonder how much of a time difference single quotes vs. double quotes makes? Either way, thanks for the suggestion.

Running this code: `use Benchmark qw(cmpthese); cmpthese(10000000, { single => sub {$foo = 'http://www.yoursite.com'}, double => sub {$foo = "http://www.yoursite.com"}, });` [download] produces these results on my machine: `Rate double single double 2865330/s -- -2% single 2915452/s 2% --` [download] So it looks like single quotes may be slightly faster, but that may be within the margin of error. I generally use single quotes unless I need interpolation of variables, but it's probably just a matter of preference. -- Mike `-- just,my${.02}`	[reply] [d/l] [select]

use Benchmark qw(cmpthese);
cmpthese(10000000, {
  single => sub {$foo = 'http://www.yoursite.com'},
  double => sub {$foo = "http://www.yoursite.com"},
});
