This should also work:
>>probe get in get to-word "system" to-word "options"
To check if it is poluting the Global Namespace:
>> probe do in get to-word "system" to-word "options"
make object!
<<cut out to save space>>
binary-base: 16
cgi:
make object! [
server-software: none
<<cut out for space>>
content-length: none
other-headers: []
]
]
>> ? cgi
Found these words:
decode-cgi (function)
>> ? get in system/options 'cgi
USAGE:
GET word /any
DESCRIPTION:
Gets the value of a word.
GET is a native value.
ARGUMENTS:
word -- Word to get (Type: any-word)
REFINEMENTS:
/any -- Allows any type of value, even unset.
== cgi

This is because 'system/options is of the datatype Path!. I am not
currently certain of the solution. I will toy with & let you know what I
find. ;)
