Value of properties can be expression.
Example found in the 2007.03 Liberty Reference Manual that was also found
in the wild:
input_voltage(CMOS) {
vil : 0.3 * VDD ;
vih : 0.7 * VDD ;
vimin : -0.5 ;
vimax : VDD + 0.5 ;
}
Current implementation just parses the expression but no interpretation is done.
