History

David Majda a4a66a2e5b Switch from first/rest to head/tail in the PEG.js grammar In the past year I worked on various grammars where first/rest or head/tail were used as labels for parts of lists. I found I associate head/tail with a list immediately, while in case of first/rest I have to "parse" grammar rules for a while before understanding their structure. Moreover, I tend to assume that rest is a list of the same thigs as first, but I don't have such assumption in case of head/tail. This assumption was in conflict with the grammar structure. I'm not sure how much these observations are applicable to others, but I decided to act on them and switch from first/rest to head/tail.	9 years ago

In the past year I worked on various grammars where first/rest or
head/tail were used as labels for parts of lists. I found I associate
head/tail with a list immediately, while in case of first/rest I have to
"parse" grammar rules for a while before understanding their structure.

Moreover, I tend to assume that rest is a list of the same thigs as
first, but I don't have such assumption in case of head/tail. This
assumption was in conflict with the grammar structure.

I'm not sure how much these observations are applicable to others, but I
decided to act on them and switch from first/rest to head/tail.
