Just thought I'd mention you can also use \ at any time to escape an alias:

% alias lt="one two"
% eval '\lt() { echo foo }'
% which lt
lt: aliased to one two
% unalias lt
% which lt
lt () {
	echo foo
}
% alias lt="one two"
% which lt
lt: aliased to one two
% lt
zsh: command not found: one
% \lt
foo
% l\t
foo
