I thought that qr was mainly used for pre-compiling variables into
regex patterns, but a colleague uses it like so:

my ( $name, $value ) = split qr/=/, $string;

Are there any benefits to doing this?

Not that I can see.

He claims that the use of the
qr// op here can help capture an error if the STRING is not a valid
regex.

I have no idea what "capture an error" might mean...

Does this make any sense?

No, unless he can give an example where using qr// gives more
info than an m// with the same pattern.

These both make the same output for instance.

perl -e 'qr/(/'

and

perl -e 'm/(/'

Can your colleague provide a counter-example that shows qr// as
somehow "better"?
