name "reSt" in debugger

[Douglas Bates]

I keep getting an error message about "return" inside the debugger
when I try to work with an object called reSt.  Here is a transcript
 R> debug( createConLin )
 R> createConLin( distance ~ age, Orthodont, ~ 1 | Subject )
 debugging in: createConLin(distance ~ age, Orthodont, ~1 | Subject)
 debug: Call <- match.call()
 Browse[1]> 
 debug: if (!inherits(fixed, "formula") || length(fixed) != 3) {
	     stop("\nFixed-effects model must be a formula of the form \"resp ~ pred\"")
 }
 Browse[1]> 
 debug: REML <- FALSE
 Browse[1]> 
 debug: reSt <- reStruct(random, REML = REML, data = NULL)
 Browse[1]> 
 debug: groups <- getGroupsFormula(reSt)
 Browse[1]> reSt
 Error: No function to return from, jumping to top level
 Browse[1]> class(reSt)
 [1] "reStruct"
 Browse[1]> print(reSt)
 Error: No function to return from, jumping to top level
 Browse[1]> print(get("reSt"))
 Error: No function to return from, jumping to top level
 Browse[1]> length(reSt)
 [1] 1
 Browse[1]> formula(reSt)
 Error: No function to return from, jumping to top level

Is there something magical about "re" inside the debugger in the same
way that "c" means continue and "n" means next?
