The eventloop procedure allows you to execute tcl commands with immediate full error reporting. For example:

// This is an invalid command executed before eventloop
% set bla [string len]
wrong # args: should be "string length string"

// This is an invalid command executed after eventloop
%eventloop
Type "exit" to exit the event loop
% set bla [string len]
wrong # args: should be "string length string"
while executing
"string len"

As for proc pp, proc pv, proc pn and proc indent:

pp - print proc
pv - print variable
pn - print namespace (with procs, variables and proper indentation)
indent - apply indentation based on open/close braces

You can test them, for example:

% proc bla {a b c} {
set a [expr {$b+$c}]
}
% pp bla
proc bla {a b c} {
set a [expr {$b+$c}]
}

I'll appreciate of someone will explain with few small examples please?
