Perhaps someone could explain to me why calling

proc Save {} {
set fh [ open "test" "w" ]
puts $fh message
close $fh
}
Save

is working, but:

namespace eval textile {}

proc textile::Save {} {
set fh [ open "test" "w" ]
puts $fh message
close $fh
}
textile::Save

shows the error: <wrong # args: should be "open">

Most likely you have a textile::open taking no arguments.
The snippet above doesn't generate any error when run in isolation.

Meaning, the call to "open" should really be "::open"

You have to be a bit careful calling Tcl core commands when inside a
namespace.
