#!/usr/bin/perl -na

$k = shift @F; print "$k $_\n" for @F

Mine doesn't care about the contents of the fields, only the positions.

Neither yours nor mine will handle the input below, which the OP asked about in response to another suggestion.

#!/usr/bin/perl -na

$k = shift @F; print "$k $_\n" for @F ? @F : ''
