Re: [FishMonger] Recognition of numbers

Yes, I did test this in a separate script using several input patterns but could never reproduce this behavior.

As it may happen depending on the incoming data that $params_in->{resolve_until_release} will either not exist or be any string or be the empty string or even undef, I use the construct ($var || '') quite often in comparisons and pattern matching; that will eliminate one additional variable or one if clause or one condition and possibly some brackets for the rest of the conditions. I tend to think that this is easier to read, because it becomes clearer what actual problem is dealt with in the complete if-clause. But I agree that this is arguable.


Anyway, thank you very much for your good advice, I will browse through my code and restructure all statements where $1/$2 are used so that they are only evaluated in the block after the condition and not inside the condition.

Best regards,
Mike
