The idea is avoiding clashes between variables and constants, like this:

\starttext

\setupmathematics[default=normal]

$𝑒 = ∑_{𝑖=1}^∞ e^{i-𝑖}$

\setupmathematics[default=italic]

$𝑒 = ∑_{𝑖=1}^∞ e^{i-𝑖}$

Very, very poor mathematical style...

If you really want to use a variable "e", this would call for the use of the function \exp() to be readable.

Unicode has added characters to enable such writing. Also, \exp is already defined to “exp”, for example for the exponential map in differential geometry: \startformula \exp_x: M_x → M \stopformula Here, the “:” expands in original TeX as a ratio operator, but Unicode has a special symbol for that, ∶ RATIO U+2236.
