i will reflow the quasi-quoted text to 90 columns wide. If an interpolation variable is on its own line and expands to a multi-line string, the interpolated text will be indented the same as the interpolation variable was:

:set -XQuasiQuotes
:{
a = "Multi\nLine\nString"
b = [i|
    This line will be reflowed
    and the interpolated
    multi-line string here:
        #{a}
    will be indented. This
    text is outdented again.
  |]
:}
putStrLn b

This line will be reflowed and the interpolated multi-line string here: Multi Line String will be indented. This text is outdented again.
