I fully agree with you.
I think it is imortant to have the abilit to write math expressions shortly:
May be it is obvious question:
If it is easy to add ‘_’ s to number literal it may be easy to implement somethink like:
val a = 1.5$bd+5$bd*115$bd
Or with any other no letter symbol?
I think it will be more comfortable but it’s not very important. In such case we can use string interpolation:
val a = bd"1.5"+bd"5"*bd"115"
