But isn't it already as of f90? I mean to say that in f90
programming, almost all the code is in modules, and typically
one puts an implicit none statement after all the use
statements in the module. All the module procedures accordingly
inherit the implicit none state from their host module which
must be overridden with implicit statements in each module
procedure if (as is sometimes the case) implicit typing is
actually desired for the given procedure.
