To link your code with LGPL code, you effectively must either provide
the user with object files for your code, or arrange for the LGPL code
to be contained in a shared library (the actual requirement is that
the user be able to modify the LGPL code and obtain a version of your
program that uses these modifications).  The former option is a
significant cost in terms of how annoying it is to distribute your
code.  I don't know if the latter is even possible -- can all the
Haskell implementations create shared libraries?

At any rate, while it is certainly possible to link proprietary code
with LGPL code, I wouldn't say that the combination is "without any
problems".
