This is  probably not what you want. puneet here is a variable name not
a string. You should output a valid GP string. 

Use
extern("printf '\"%s\"' `uname -n`")

I do not thing it is fair to call that an 'immediate evaluation'.
extern is the equivalent of read() for pipe. What you want
is something completly different.

Cheers,
