A friend of mine, just tossed me this link.. http://ideone.com/

What makes Ideone different from any other pastebin is its compiler feature; Supporting about 20 programing language, you will be able to live compile (of course with some limitations) your code.

Let’s find out the perl version running on that server

print $];

and result?

result: success
time: 0s    memory: 3248 kB    signal: 0
input: no
output:

5.008008

Ok… not the 5.010000 I excepted but not too obsolete either.

Have fun,
