Yes, but in Fortran 90 "==", ">="  etc. are equivalent to ".EQ." and
".GE.". It is also possible to define operators on native and
user-defined types, so that

Y = A .tx. B

can be written instead of the expression with the F90 intrinsic
functions

Y = matmul(transpose(A),B)

The Fortran 95 package Matran at
http://www.cs.umd.edu/~stewart/matran/Matran.html uses this approach to
simplify the interface of the Lapack library and provide syntax similar
to that of Matlab and Octave.

I don't know if the syntax of your idea clashes with Python, but it is
viable in general.
