Your experience with Fortran is dated -- see below.

Gfortran, which supports Fortran 95 and a little of Fortran 2003, is
part of GCC and is thus widely available. Binaries for g95, also based
on GCC, are available for more than a dozen platforms, including
Windows, Mac OS X, and Linux. I use both and consider only g95 mature,
but gfortran does produce faster programs. Intel's Fortran compilers
cost about $500 on Windows and Mac OS and $700 on Linux. It's not
free, but I would not call it costly for professional developers.

Speaking of money, gfortran and g95 have free manuals, the latter
available in six languages
http://ftp.g95.org/ . Final drafts of Fortran standards, identical to
the official ISO standards, are freely available. The manual for Numpy
costs $40 per copy.
