Document N2146 toward Fortran 2018 DIS has in section 11.1.4 BLOCK
construct a constraint:
C1107 (R1107) A block-specification-part shall not contain a COMMON,
EQUIVALENCE, INTENT, NAMELIST, OPTIONAL, statement function, or VALUE
statement.
whereas 10-007r1 toward Fortran 2008 has in the corresponding section 8.1.4:
C806 (R807) The specification-part of a BLOCK construct shall not
contain a COMMON, EQUIVALENCE, IMPLICIT, INTENT, NAMELIST, OPTIONAL,
statement function, or VALUE statement.
Am I correct in viewing this as a change with respect to the IMPLICIT
statement in a BLOCK construct in Fortran 2018?
But I did not notice any direct mention of this as an extension to
Fortran 2008 in the Introduction section of N2146. Is it not
necessary or is it implied (!) by some other sentence(s)?
I will appreciate any comments or feedback on this aspect with respect
to Fortran 2018 and the standard document.
Thanks and best regards,
