Came up during code review today.
</P>
<P><B>1. Initializing a hash</B></P>
<P>
Given something like:
<CODE>
my @tests = ( "tfred", "tjock", "tfortytwo" );
</CODE>
do you prefer:
<CODE>
my %ntests = map { $_ => 0 } @tests;
</CODE>
or:
<CODE>
my %ntests;
@ntests{@tests} = (0) x @tests;
</CODE>
</P>
<P><B>2. Setting a string to a value or the empty string</B></P>
<P>
Do you prefer:
<CODE>
my $mol = "forty two" x ($n == 42);
</CODE>
or:
<CODE>
my $mol = ($n == 42) ? "forty two" : ""
</CODE>
</P>
<P>
Please feel free to suggest alternative solutions.
