＞Lispの歴史の中でのSchemeの位置づけについて

Gerry Sussman and I wanted to understand Carl Hewitt’s ideas, which seemed to have intellectual power, but we couldn’t get past the complexity and the notation to see “what was really going on.”
So we decided to implement a “toy” actors language.
We hoped that it could capture the essence of the ideas while remaining simple enough to understand.
It might even turn into something useful.
