Hi all,
Here is a N00B question, but I can not find the answer by Googling, or
reading Stuart's book. So, I assume that others will want to find this
FAQ in the future.
I am calling legacy code, and I need to set the level on the Java Logger.
In Java it would look like this

RE: Side Effects
What about logging? Without a debugger I use lots of print's to debug

Hey all,
What is the idiomatic way to concatenate strings? Here are some things
that I expected to work, but didn't
(+ "foo" "bah")
(conj "foo" "bah")
(into "foo" "bah")
For the moment I am doing
(.concat "foo" "bah")
But it seems wrong
Thanks

Here's a dumb question, but I can't find it in the docs:
How do I get the length of a sequence? Is there some generic way to
find the number of elements in something that might be list, map, vector

There must be some sort of built in function, or an idiom

Excellent!
How is the Clojure compiler tested? Is there a set Clojure code that

Actually, the observation below might be really good news. Does it
means that all references are resolved at compile time? Do I ever have
to run the code to figure out the context of a reference? Or, does the
lexical context give me all the information I need?

Hello, and thanks for all the help with the IntelliJ plugin.
The next feature I want to implement is "references". That is, one
selects a symbol, and then can go to the location where that symbol was
defined (e.g. def, defn, let, etc.). One can also get a list of all the
locations where that
code was marked as an error. Please report all cases, with an
S-Expression to opus...@gmail.com.
To install go to Settings/Updates and add the following to Plugin Hosts

Hi Justin,
This is the right place. Thanks for trying the plugin.
It would absolutely be helpful to document use of the plugin. However, I am

Of course, having done that, you could help
