 > what with the 2x space?

Something I like about Source Code Pro is the greater spacing between 
identifiers. In comparison, I found DejaVu Sans and Source Sans Pro to 
be too dense, especially so with the latter.  So I experimented with 
doubling the size of that space with the proportional fonts.  I just 
Search-Replaced <space> with <space-space>, but in an IDE you could use 
one of the wider space character like the EN-QUAD [5].  Except the 
performance with Unicode versus ascii characters would need to be 
checked.  I've attached a some more comparisons of identifier spacing. 

Sorry I mislead you with the Source Sans Pro 2X-spacing in previous 
PDF.  You wont get that exactly out of the box without some code changes 
to use a wider space character.  Check you opinion against the 1X-spacing.
