// if the resultMap size is less than or equal to zero
// then the product is added
if (resultMap.size() <= 0)

下面是一个必须声明的局部变量，只是为了将一个常量传递给库函数:

// This only exists because Scott doesn't know how to use const correctly

/* My lawyer told me not to reveal */

# There is a bug in the next line.  $searchParameters != {} will always return true, because {} is creating
# a new hash reference on the fly, and the inequality operater is comparing the memory location of it
# to the memory location of $searchParameters, and they will always be different. 
# This means that the following code will always get executed as long as $nodes is defined.
# I'm leaving it there because it has always been there, and although I'm sure it was originally meant to
# mean %$searchParameters (essentially "is this hash not empty"), I'm afraid to change it.
if ( $nodes && $searchParameters != {} )
{

map(TimeZoneId.Romance, "Romance Standard Time"); //LULZ.

在一个生成HTML的旧perl脚本中找到:

# I would be _very_ brain farting if I said this code didn't need reviewing.
# It will make babies cry, and hair grow on your back, so please don't use it
