Description:
Here documents and interpolated strings via quasiquotation; documentation
This library adds support for multi-line string literals (a.k.a. "here docs") and string interpolation to Haskell via GHC's QuasiQuotes extension. The quoted expressions behave like string literals in the source code; that is, they produce values of type String, or, with the OverloadedStrings language extension enabled, values of type IsString a => a. . This package provides the documentation for a library for the Haskell programming language. See http://www.haskell.org/ for more information on Haskell.
