[Jprogramming] What are the strangest features of J?

[Henry Rich]

I want to add an early section my book which will
be titled "Culture Shock" and will contain the most surprising
things a C (or Java) programmer would encounter.  I'd appreciate
additions to this list, which I started by using Raul Miller's
essay:

0.  { } [ ] " as verbs
1.  . : as inflection
2.  no statement delimiter
3.  no declarations; any noun can be an array
4.  bivalent verbs; only 2 function operands; x. and y. as reserved words
5.  A list of numbers is a single word
6.  modifiers (adverbs and conjunctions)
7.  Looping using modifiers rather than control structures
