He? You have initialized "a" correctly at the beginning, but overwritten by a character vector. Now it is no longer of class "tclVar", so what do you expect?
I guess you are going to use something like
tclvalue(a) <- "pipo" tclvalue(a)

Error in structure(.External("dotTcl", ..., PACKAGE = "tcltk"), class =
"tclObj") :
[tcl] can't read "pipo": no such variable.
