interpExp :: String -> Q Exp

interpExp performs very simple interpolation of Haskell values into Strings.

• Interpolated variables are prefixed with $
• They can optionally be surrounded with braces like ${foo}
• Interpolated variables are converted to strings with show
• To escape a $ use \$

>>> let foo = 123 in $(interpExp "hello, $foo")
"hello, 123"

>>> let foo = "world" in $(interpExp "hello, \\$foo")
"hello, $foo"

>>> let foo = "world" in $(interpExp "hello\r\n\rworld")
"hello\r\n\rworld"
