I think that actual use cases are rather belongs to numeric area.
For example, one could use infinity symbol when output infinity numerical 
results of calculations to the text file and another one input them. 
Usually float numbers in python world are converted from string using 
float(...). So any code that use float to convert from string could benefit.This 
is not a real use case though, but rather some scenario...
