i'm using some tools built by someone else in my group, and these tools are littered with stuff like this: 

eval "use Foo::Bar::Baz;";
die if $@;

[download]
the only reason i can see for these: the module being included isn't used in any other place but that sub.

this strikes me as a _bad_ idea, but it's more of an instinctual feeling than anything else.

i know that calls to 'eval' can be expensive, but is this a good way to use them?

i've used the block form of eval frequently, but this doesn't really look like an error that needed to be wrapped in an eval. i know that the memory footprint of the module in question would be a bit larger by adding the 'use Foo::Bar::Baz;' at the beginning of the module ( the more traditional way of 'use'ing modules ), but is that, in itself, a valid justification for this kind of runtime 'use' statement. ..
