There are not many ShoutTests that could ensure that I'm no the right
And Shout code is hard to read for me (see below).
It's also strange to have to change such a central method after all these
years of service.
Many reasons for a stage in inbox, if ever a few pairs of eyes are browsing
I find this Shout Parser selector particularly misleading...
It's hard to guess that #isSelectorCharacter: is going to check
exclusively for binary selectors before I browse the implementation details.
Should it be named #isBinarySelectorCharacter:, I could eventually omit
In a lesser way, I also do not like self isName, self isBinary, self
The intention is to check for the currentToken, not self.
They have the advantage of being short, but reading the code gives a
If I wanted to avoid the heavy isCurrentTokenAName,
isCurrenTokenABinarySelector, isCurrentTokenAKeyword, ... maybe I would
just use has instead of is?
I've also ran the Shout Parser through a Debugger, and I encountered a lot
of redundancy during the tokens scan (those isName isKeyword... are ran
several consecutive times).
