如果没有特殊字符，我想在分隔符前面拆分if

my $str = "a,b,c,d,e";
my @lst = split (/,/, $str);

# gives me: ("a", "b", "c", "d", "e")

# now I want to split after any , with not a character c in front of the ,.
# ("a", "b", "c,d", "e")

我试过了

split (/(?!c),/, $str)

但它没有按预期工作。

用于向后检查的功能

split (/(?<!c),/, $str)

split（/（？）？
