</span>What you mean by practical? Does it mean that you can find enough people<br>
able to use it in your real-world project, without putting too high<br>
requirements on training them?<br>
<br>
If so, then we could say that given the current state of affairs, where<br>
the mass of okay programmers are trained on a different paradigm,<br>
Haskell is not all that practical.<br>
<br>
But if practical means that the language is well suited for solving<br>
real-world problems, in beautiful ways, once you get it, then it is<br>
uberpractical! :-)<br>
