(I've done a basic Google search on this with no results. Apologies if this has
been asked before.)
I am coding a web application in which the content is a Unicode string built up
over multiple functions and maintained in a State structure.
I gather that the String module is inefficient and that Data.Text would be a
better choice.
Is it more efficient to build up a list of Text objects over time and combine
them together with a single Data.Text.concat for the final output or to run
Data.Text.append for each new string so that I am maintaining a single Text
object rather than a list?
As Data.Text.append requires copying both strings each time, my gut feeling is
that concat would be much more efficient, but Haskell has surprised me before,
so I wanted to check.
