I'll go one step further and say that we shouldn't have to call
persist namespace. It should be automatic such that a change to the
state of an identity is transactionally written.
Let's start with refs. We can tackle the other identities later.
The API is simple. Call (refp) instead of (ref)
While examining the Clojure source I came across this line in the
EmptyList class:
public boolean equals(Object o) {
return (o instanceof Sequential || o instanceof List)
RT.seq(o) == null;
}
What's up with the RT.seq(o) == null? Why don't we do this instead:
public boolean

Thanks! That worked for me. Understood on the precautions about these
things not being immutable, and thus potentially unsafe as hash keys (and
anything else that expects immutability, whether that is obvious or not).
This raises the question in my mind -- will there be something in Clojure,
Persistant variable handling is one of the things which I have spent much
time on as a beginner and former SQL-illiterate (Among getting the swank to

I defined a fn whose execution depends on the number of parameters
passed to it. It works fine! I am just concerned that I am doing
this in a way that is not as concise as it could or should be. Here

Hello Glen,
I'd use the first two forms to set startidx and size and then call the
full form:
(def inf java.lang.Double/POSITIVE_INFINITY)

Parses text file for single sweep specified by sweepidx. If size

not specified will parse till end of sweep. If startidx and size
It checks the value against memory. If it's
the same, commit data store changes. If not, retry after refreshing
memory with the current contents of the store.
May I suggest we take a page from the CouchDB book here? In addition
to having a id each ref also has a revision id. Let's say the id

Probably so the list can be compared to anything and thus o may not
implement Seqable, like:
user= (.equals '() nil)

Hi.
I'd like to do a union of some sequences using my own comparison
function. Similar to supplying a Comparator in Java. The things
being compared are Objects from a Java library that I don't control,
so I can't just override the equals function on the class, for
example.
Would aprecaite any
Ah...so I looked into the RT code a bit more and you're right. If we
passed in a Java array or a Java String then it would need to be
converted to a Seqable class first then we could have a seq() method
to call.
Thanks,
Timothy

Awesome! It doesn't have to be much. Searching for examples and docs
is the most important thing, obviously. I'd request that if you're
going to have any single format, JSON would make me the happiest.
Clojure data structures would be cool, but that's kind of limited to
Clojure.
