Re: Strange behaviour of tr function in case the set1 is supplied by a variable

[likbez]

With eval statement works correctly. So it looks like $ is treated by tr as a regular symbol and no warning are issued.

$statement='$diff1=$str1'."=~tr/$str2//;";
eval($statement);
print "With eval: diff1=$diff1\n";

that will produce:

With eval: diff1=3
