GOTO as a keyword doesn't need to be provided for GOTO as functionality to exist. Whenever you call a subroutine, some form of GOTO activity occurs. Whenever you do a conditional, GOTO occur. For example, a simple if-statement can break down to the following: 
if ($x) {
    statement1
}
else
{
    statement2
}

--------

JZ $x ELSE1
statement1
JMP IF1_DONE
ELSE1:
statement2
IF1_DONE:

(JMP used in place of GOTO, to continue the ASM-style operators.)

Every if-statement is equivalent to the above ASM-style layout. while and for are similarly rewritable (and, in days gone by, would have been rewritten to exactly that in the ASM equivalent, at least for x86 and PDP-11, which are the only ASMs I'm familiar with). All subroutine calls (which is Unlambda) are performed by GOTO-type functionality.
