$ ghci -fth VariableExpansion.hs

"7"

"Here is my url: \"http://www.google.com\";. Do you like it?"
Cheers,

Yes, just like that ;-) Thanks!
Now if somebody has a string interpolation library, I'd be a pretty
happy camper ;-)

Is there any support for multi-line string literals in Haskell? I've
done a web search and come up empty. I'm thinking of using Haskell to
generate web pages and having multi-line strings would be very useful.
Do you mean like this:
string = " line one\n\
\ line two is here\n\
\ line three is this line\n"
$ echo 'putStr string' | ghci A.hs
line one
line two is here
line three is this line
