AS3/Flex StringUtil.substitute

gistfile1.as

StringUtil.substitute("ClassName [name={0}, key={1}, field={2}, etc={3}]", name, key, field, etc);

/*
StringUtil.substitute is a useful print formatter tucked away in the Flex SDK, if you're used to printf in C or String.format() in C# you'll be glad to find this 

Whatever the case, rolling a complex string in AS3 is much easier with this than the alternative.

e.g. 

"ClassName [name=" + name + ", key=" + key + ", field=" + field + ", etc=" + etc + "]";

Which is pretty horrible, but I'm sure you've had to build 100's or 1000's of strings like this.
