What about:

   puts "[expr {0 == 0}]"

What is this going to return in your tclsh?
Is it going to say

    true
or
    t
or
    yes

?

NO. It is printing:
1

It will NEVER print anything else. Hence you cannot
test string equality for expressions with "false"/"no" etc
but you CAN test it with numerical value of 0 (zero)
or non-zero.

Allright?
