           Summary: Safer number literals
           Product: D
           Version: 2.040
          Platform: Other
        OS/Version: Windows
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: bearophile_hugs eml.cc



Octal numbers are not common, but sometimes less experienced programmers can
add leading zeros to align numbers or for other purposes, and this can cause
bugs:

int x = 010;
This assigns x to value 8. 

To avoid that bug D can turn leading zeros in syntax errors (for safety with
code ported from C to D), and a safer syntax can be introduced for octal
literals, for example like in Python3 (or some other syntax can be invented):

0o10
0O10


Optionally D can also turn FP literals like the following into syntax errors:
.5
3.
To require something like:
0.5
3.0
But this is less important than the octal syntax.
