Re: [sv-bc] Implicit generate block for loop construct inside conditional construct

No Daniel. As per LRM, if begin-end is missing for loop generate construct, an implicit begin-end scope is created.

Is there begin missing inside for loop - as far as I know this begin end in
generate for loop is obligatory:

 module top;
     if (1) // Will it create an implicit named block or not
         for (genvar g = 1; g < 10; g++) begin
             reg x;
         end
     int b;
 endmodule

Hi,
If we consider the case:
module top;
    if (1) // Will it create an implicit named block or not
        for (genvar g = 1; g < 10; g++)
            reg x;
        end
    int b;
endmodule

LRM mentioned for conditional construct directly nested inside another 
conditional construct does not create separate scope. I think then 
looping construct directly nested inside another conditional construct 
should create then a separate scope. Can you please confirm. If the 
answer is yes, then also for that block, name will be generated as per 
name generation scheme for unnamed generate block mentioned in the 
LRM.
