[Sc-devel] environment-safe functions

[James Harkins]

Works for me, thanks. I will probably keep the e short form in my  
library, especially since there is already the precedent of single  
letter methods for Function -- if we can have p and r, why not e? :)   
But I won't ask for that to go into the main library.

Oops... I just read this more carefully. It won't work. You have to  
save the environment outside the returned function. The whole problem  
is that currentEnvironment is not the expected environment inside the  
function!

+ Function {
	inEnvir { |envir|
		envir = envir ?? {currentEnvironment};
		^{ |... args| envir.use({ this.valueArray(args) }) }
	}
}
