Summary: defer syntax errors to execution time

Initial Comment:

% proc test {} {
            proc if {a b} { uplevel 1 [list set $a $b] }
            set 1 {syntax {}{}}
            if 1 {syntax {}{}}
        }
% test
extra characters after close-brace

The compile time report of the
syntax error prevents this proc
from running, and when it runs,
there's no longer a syntax error.

Here's a patch that defers
syntax error reporting to
execution time.
