print join "," => @to_print;
[download]

I never saw this ! Does this means that one can use => instead of a coma everywhere ?
Is there a precedence difference ?
I'm used to do :

print join(",", @to_print)
[download]

which is obviously less idiomatic .

=> is almost the same as , The difference is that => forces the value to the left of it to be interpreted as a quoted string This is why `#!/usr/bin/perl -w my %a=( foo => "bar", fi , "fo");` [download] Will get you a warning for the unquoted fi, but not the unquoted foo. However, normal operator precedence still applies, so `print join , => @to_print;` [download] won't work, whereas `print join or => @to_print;` [download] will.	[reply] [d/l] [select]
