(j3.2006) entities declared in block constructs

[Malcolm Cohen]

On the contrary, this is no defect in nagfor (which anyway does not yet conform to a standard that will be published in the future!), but is a defect in the draft.

Looking back, it is a copy-paste error: the ?[ <implicit-part> ]? line should not have been copied into <block-specification-part>, indeed 15-137r1 which did this edit specifically says NOT to include it!  The omission of <implicit-part> is what lets us omit IMPLICIT in the list of statements that are not permitted.  The editor?s report makes no mention of a deliberate change here, so it was accidental sabotage not deliberate.

This defect in the 007 needs to be corrected.

(It is obviously a defect for many reasons, including that there is no mention of this alleged new feature in the Introduction.)

Cheers,

It looks like IMPLICIT is permitted in a BLOCK construct, and whichever
version of nagfor that Malcolm used to test the proposition has a
defect. The third line of R1109 <block-specification-part> is
<implicit-part>, which gives the syntax for a sequence of IMPLICIT (and
other) statements. So that brings back Erik's original question.
