try for example 

<?php @nonexistant_function(); echo "done\n"; ?>

and you won't get any ouptut at all
because execution is terminated due to 
calling a nonexistant function

i just spent a lot of time debugging a set of 
script that denied to work on a server without
giving any information about whats wrong only 
to find out that somewhere nested deep within
all the files that got included was a 

  @OCILogin(...)

and this cauesd the script to die silently as 
no Oracle support was available in the PHP
build i used ... :(

Well, why won't you use error_reporting setting then? Also, you might use report_error and log_errors (not sure those are exact names) to log errors only to logfilke and not to screen. @ is means to make it "real silent" not just "don't report unnecessary errors".

The purpose of the '@' is to turn off errors surrounding the function and leave you to do the checking.

yes, but on *critical* errors (and i was refering 
only to those) php terminates so that i have no
chance to check anything

this is what this report is about

This is certainly not a misbehaving function problem!
 [2000-07-28 18:19 UTC] hholzgra@php.net 
so i would suggest the following patch:

zend_execute.c line 2330ff
  case ZEND_BEGIN_SILENCE:
    Ts[opline->result.u.var].tmp_var.value.lval = EG(error_reporting);
    Ts[opline->result.u.var].tmp_var.type = IS_LONG;  
-   EG(error_reporting) = 0;
+   EG(error_reporting) = E_ERROR | E_USER_ERROR; 
    NEXT_OPCODE();

or maybe we could add another error type
called E_UNIGNORABLE_ERROR ...

The purpose of @ is to silence all down
