Be careful! If the input is untrusted, that snippet could execute arbitrary code. (Consider `my $m = '); arbitrary perl command here';`) Be sure to place big red arrows in your comments. String::Interpolate might be safer.	[reply] [d/l]

String eval does the trick. In addition to the other solutions that avoid string eval and its inherent risks, there's YAML::Syck`::Load` although that's probably an overkill: `print Load '--- "Hello\nWorld\n"';` [download]	[reply] [d/l] [select]
