Using Python's built-in defaultdict we can easily define a tree data structure:
def tree(): return defaultdict(tree)That's it!
先前在《開源應用程式架構》 一書中，我介紹了 SocialCalc 這個在瀏覽器中運行的試算表編輯器，以取代伺服器為中心的 WikiCalc 架構。SocialCalc 在瀏覽器中執行所有的運算，只有在載入和儲存試算表時才會使用伺服器。
追求效能是 Socialtext 團隊在 2006 年時設計 SocialCalc 的主要目的。重點在於：在 JavaScript 環境下執行客戶端運算，儘管在當年的速度僅有伺服器端 Perl 運算的十分之一，但仍然勝過 AJAX 來回傳輸資料造成的網路延遲：

Comparing cache-miss of triez, fast_trie and hash reads
To test out the cache miss behavior of read operations, run a program building the index (30k entries) then another program building then reading the index (30k queries), and find their diff.
Here's how to generate the test script cmd.sh
3.times do |i|
%w[triez hash da].each do |ty|
puts "valgrind --tool=cachegrind --cachegrind-out-file=tmp/#{ty} ruby t.rb #{ty}"
puts "valgrind --tool=cachegrind --cachegrind-out-file=tmp/#{ty}.read ruby t.rb #{ty} read"
puts "cg_diff tmp/#{ty} tmp/#{ty}.read > tmp/#{ty}#{i}.diff"

Basic principles of using tcl-expect scripts
TCL-Expect scripts are an amazingly easy way to script out laborious tasks in the shell when you need to be interactive with the console. Think of them as a "macro" or way to programmaticly step through a process you would run by hand. They are similar to shell scripts but utilize the .tcl extension and a different #! call.
The first step, similar to writing a bash script, is to tell the script what it's executing under. For expect we use the following:
#!/usr/bin/expect
