The LaTeX package unicode-math has an option colon=literal, which makes it behave as in math functions (as in example below). Has ConTeXt a similar option?
No. You have to use \colon.
It would be nice with such an option, as it helps the readability of the input files.
already for some years i'm thinking of something similar to openmath 
dictionaries i.e. in many cases when one writes math it is in some field 
that is consistent within a document, say logic or engineering

it is rather trivial to support something

\setupmathematics[domain=logic]

or so, where we automatically relate the math class with the symbols 
used, something that becomes more important once we start coding in 
unicode instead of using names

but ... in order to provide this, i need information about useful 
categories

i had planned this for later this year but anyway uploaded a beta that 
has an experimental feature (this is something to discuss at the 
upcoming context meeting)

\startluacode
     mathematics.registerdomain {
         name       = "foo",
         parents    = { "bar" },
         characters = {
             [0x3A] = {
                 char  = 0x2236,
                 class = "inner"
             }
         }
     }
\stopluacode

\startTEXpage
     $a: b$\par
     \setupmathematics[domain=foo]$a: b$\par
     \mathematics[domain=foo]{a: b}\par
     \definemathematics[foo][domain=foo]\mathematics[foo]{a: b}\par
\stopTEXpage

eventually we can consider a set of domains and a macro for defining a 
set of them etc but it all depends on use ...

i'll upload a beta
