camfort complains with double colon use statement

[wadudmiah]

Camfort complains with the code which is valid Fortran:
use :: Types_mod
with the error message:

$ camfort stencils-check Solver_mod.f90 
Checking stencil specs for 'Solver_mod.f90'
camfort: fortran-src: user error (4:9: Solver_mod.f90: parsing failed. Last parsed token: TDoubleColon (4:7)-(4:8).)

Hi Wadud,

I am not part of the camfort team, but I think that this issue should rather be reported to the fortran-src parser (https://github.com/camfort/fortran-src/, developed by the same team) issue tracker.

In any case, note that the possibility of a double colon between the use keyword and the module name was introduced in the 2003 standard [1], which is a version of the Fortran standard that camfort and fortran-src do not attempt to support yet.

[1] See R1107 of Fortran 95 vs. R1109 of Fortran 2003. Actually, it was introduced in the Floating-Point Exception Handling Technical Report, ISO/IEC TR 15580, published between both standards (see absolute page 13 in https://wg5-fortran.org/N1351-N1400/N1378.pdf).
