Some time ago there was a thread disucssing numeric ordering issues; the
fact that ℂ lacks an ordering was part of that discussion.
A recent paper on arxiv proposes inflicting an ordering on ℂ using:
,----< excerpt from http://arxiv.org/abs/1003.4906 >
| Given A = a₁ + i·a₂ and B = b₁ + i·b₂, then:
| A ≤ B if a₁ < b₁ || ( a₁ == b₁ && a₂ ≤ b₂ )
| A ≥ B if a₁ < b₁ || ( a₁ == b₁ && a₂ ≥ b₂ )
I wonder whether having such an ordering available would be beneficial
for Perl, or for coding in general?
