Although, sometimes it works. I don't know exactly what conditions triggers it. Maybe it depends on where the error is, what type of error it is, or something else. Sigh. On Friday, May 2, 2014 6:06:59 PM UTC+2, Oskar Kvist wrote: > > Hi! > > I'm using Vim, vim-fireplace, `lein repl`, and tools.

Hi! I'm using Vim, vim-fireplace, `lein repl`, and tools.namespace. When I run `(tools.namespace.repl/refresh)` from within vim via fireplace, it usually (perhaps always) works the first time. Say there is a simple error like a misspelled word. The second time I try to run `(tools.namespace.re

Converting sequence from sort into a list

I have a sequence from a call to 'sort'. I want a list. What is the best way to do this? (apply list (sort ...))? Will it have problems on large sequence inputs? I can't use (into () (sort ...)) since that conjoins and ruins the sort order. -- You received this message because you are subsc
