Since eclasses are associated with a learning curve, would it not be |
| 32 |
preferrable to recast the whole inheritance thing in a proper |
| 33 |
object-oriented language and rather build a support framework for it there |
| 34 |
? |
| 35 |
|
| 36 |
For instance, use scsh (okay, okay, so Scheme might not be popular with |
| 37 |
the crowd) or Python. If you take a look at SCons, you'll see Make recast |
| 38 |
into Python, with all the benefits that gives you (stable, clean, |
| 39 |
well-known language, lots of documentation, lots of support libraries, |
| 40 |
cross-platform runtime). |

Just stirring things up since the eclasses debate seems to be coming |
| 43 |
regardless. |
