Do you ever desire literals for byte, ubyte, short and ushort integrals (beside
the currently present for int, uint, long, ulong that are 10, 10U, 10L, 10UL)?

Because of the more strict typing of templates in some situations I have had to
write things like:

cast(ubyte)100

Possible literals for byte, ubyte, short and ushort integrals (the byte ones
aren't great):
10Y
10UY
10S
10US

Are similar suffixes useful enough to have?

Bye,

I would support this gratefully. I find it a big weakness of D that its 
literals do not map to a type.

As for precise morphology, I'd prefere
* instead of cryptic suffixes like 'Y' or 'S', numerous languages simply write 
the size : 8, 16, 32, 64: much nicer! A better idea would be to count the size 
in bytes: 1, 2, 4, 8.
* else, use lowercase suffixes in std, because digits are full height (so that 
the suffix is more clearly told apart)
* for the same reason, hex literals should use uppercase digits in std and '0x' 
prefix
* ideally, I would use the sign to tell signed types apart (1 is unsigned, +1 
is signed)
* get rid of "1." and ".1" horrors!
* get rif of 01 octal bug!

I hope you messed that one up. An unadorned int literal should be signed.  
Period.

Oh gods, yes.
