I agree with Hans here. The $ before the variable name is superfluous. 
In fact, the $ itself is also a shell construct originally meaning 
'variable'.

It could easily be implemented backwards compatible. Just ignore any 
initial $ signs when trying to expand a variable. The old calls would 
still work and we could promote the new style (e.g. by producing 
warnings on the old style).
