tcl - TCL lsearch の動作

Question

lsearch が動作しないという奇妙な問題。私はおそらく愚かなことをしています。どんなアイデア/助けも大歓迎です!

set mylist {}

lappend mylist a
lappend mylist b
lappend mylist c

set test [lsearch -exact mylist b]
puts "This doesn't work, result should be 1 = $test"

set test2 [lsearch {a b c d e} c]
puts "This works, result should be 2 = $test2"
