F2003 supported
ALLOCATE( A, SOURCE=B)
where the dynamic type of B determined the dynamic type of A plus where the
values where copied from B to A.
Fortran 2008 now also offers MOLD= where only the type is used, but no data is
copied.
Fortran 2008 draft FDIS: ftp://ftp.nag.co.uk/sc22wg5/N1801-N1850/N1814.pdf
R626 allocate-stmt is ALLOCATE ( [ type-spec :: ] allocation-list [,
alloc-opt-list ] )
R627 alloc-opt is ERRMSG = errmsg-variable
or MOLD = source-expr
or SOURCE = source-expr
or STAT = stat-variable
"If MOLD= appears and source-expr is a variable, its value need not be
defined."
And in the introduction one finds the following:
"A structure constructor can omit the value for an allocatable component.
SOURCE= in an ALLOCATE statement can give an array variable the bounds as well
as the value of an expression. MOLD= in an ALLOCATE statement can give a
polymorphic variable the shape, type, and type parameters of an expression
without copying the value."
