If you're having trouble remembering the order, then remember that when read aloud, you (almost) say what you mean. For example, x = 4 if b > 8 else 9 is read aloud as x ...
How do you represent a graph in Haskell?
...hat makes my brain hurt (because I haven't done much of it yet). I've done more of my substantial programming in Mercury than Haskell so far, and Mercury is strict so knot-tying doesn't help.
Usually when I've run into this before I've just resorted to additional indirection, as you're suggesting; ...

What's different about this one is the "Caused by". Sometimes exceptions will have multiple "Caused by" sections. For these, you typically want to find the "root cause", which will be one of the lowest "Caused by" sect...
MongoDB: Combine data from multiple collections into one..how?
...d documents.
This is a somewhat simple example. You can repeat this with more collections as much as you want to keep building up the reduced collection. You could also do summaries and aggregations of data in the process. Likely you would define more than one reduce function as the logic for ag...

$('#containerElement').delegate('a.myClass', 'click', function() { ... });
This, however, seems to me to be much more explicit about what is actually happening. You don't realise from the live example...

To have a deterministic threshold and more accurate filter on data, It is better to calculate 4 locations that are in radius meter of the north, west, east and south of your central point in your java code and then check easily by less than and more than SQL oper...
Neo4j - Cypher vs Gremlin query language
...
I had the understanding that Cypher was more like SQL, in that you tell it what you want, and it works out how to do it. With Gremlin, you issue exacts traversal commands, which it must obey.
