In most cases it is not necessary to write code which constructs quotations at all. Chances are you can simplify your stack effect and express what you need using built-in combinators. What are you coding?

[Factor-talk] Efficient way of adding a word in front of a quotation
Is there an efficient equivalent of "curry" to add a word to execute in front of a quotation (so that the quotation can still be compiled?) For example, does \ swap add* give a compilable quotation if the quotation on the stack can be compiled? Would "curry*" written as : curry* ( param obj quot -- obj curry ) swapd \ swap add* 2curry ; inline be as efficient as the current definition? (without considering the fact that "add*" cannot be used in the kernel) On a related topic, would the following be efficient? : curry* ( param obj quot -- obj curry ) rot [ , \ swap , % ] [ ] make ; inline Sam -- Samuel Tardieu -- [EMAIL PROTECTED] -- http://www.rfc1149.net/ - This SF.net email is sponsored by: Splunk Inc.
