Versions of packages itcl3 depends on:

itcl3 recommends no packages.

pn  itcl3-doc  <none>

-- no debconf information

Debian testing recently updated itcl from 3.4.3 to 3.4.4 and it appears SpellFix is now broken for abbreviations, eg. [info exist foo] vs [info exists foo].
For reference, Debian testing currently has tcl 8.6.13.
3.4.4 doesn't have many changes and this commit is potentially related: https://core.tcl-lang.org/itcl/info/a036f93dad15f1d4

Repro:

#!/usr/bin/env tclsh

package require Itcl

itcl::class TestClass {
    method test {}
}

itcl::body TestClass::test {} {
    set foo "bar"
    if {[info exist foo]} {
        puts "foo exists"
    }
}

TestClass testClass
testClass test
