Question: Why do you bother about delta delays?
Use "Y <= X after 1 ns" for clocked signals and you have no problem
with delta delays.

There is no construct for signal assignment, that is free of delta
delay, only variables are updated in the same tick, but I would'nt use
variables for clocks, as i find it no good idea to have a rising edge
of clock within one delta delay (would'nt suprise me, if the tools
wouldn't sup****t this propperly).
