All above explanations are correct. To understand this, try the
following:

proc testproc {} {
return "This is a test"
}

proc squareproc {} {
return "testproc"
}

[ squareproc ]

The function squareproc in my example just return the string testproc.
Note that it is just a string and squareproc does nothing special.
The interpreter will execute the first word of a line. Since squareproc
returns the word testproc then testproc becomes the first word on the
line.
