It appears based on the limited information on the website lfortran is
in its early stages.  It appears to have as a goal the ability to
execute code interactively, and as a negative is creating its own
extension to the Fortran Standard.  Also seems to require Java.

Flang on the other hand is really at this point 2 projects, both
supported/developed by Nvidia.

Flang is the current compiler that is either complete or reasonably
complete from a Fortran standpoint but requires various things to work
(a custom version of clang for example I believe).

Also included under the Flang umbrella is f18, a new Fortran compiler
being written from scratch with the goal of it being a proper member
of the LLVM community, and they have interacted with the existing
LLVM/clang community to find the best way to proceed.

In both cases (Flang/f18) they are traditional style compilers that
don't offer an interactive mode I believe.
