comments found in ObjectSpace

I ran the following code:

all = []

ObjectSpace.each_object do |obj|
all << obj
end

File.open('objectspace.txt','w') do |f|
f.puts all
end


and I was surprised to find comments in objectspace.txt. I was under the
impression that Ruby skips comments when parsing code.

Very strange behaviour... Anyone cares to explain? Thanks

simple answer: those are no comments

try:

test =3D File.open("blah.txt",'w')
puts test
test.close

I'm not sure what that code is supposed to do. Using my code, the text file
(around 152kb) that was produced contained a lot of comments, especially
from the Date class.

Oh, yeah, I know that.

have a look at line 4525
or
in the text file, search for the following string without the double quotes:
"# without specifying the format"
