So it is a hash table of symbols: variables, constants, :keywords, functions, ...? And when you do `defvar', is the symbol name inserted into this data structure based on some property - perhaps the name itself, or type (if a "symbol" isn't atomic)? Is the value inserted as well or do they use some sort of pointer scheme? -- Emanuel Berg, programmer-for-rent. CV, projects, etc at uXu underground experts united: http://user.it.uu.se/~embe8573
