Why is it an obvious footgun?

  A developer familiar with C++ may believe it to be a fixed length container (perhaps with automatic bounds checking[0]) and treat it as such in memory/security/performance critical sections. 0: https://en.cppreference.com/w/cpp/container/array/at https://en.cppreference.com/w/cpp/container/array/at

    And if they named it “vector”, a developer familiar with mathematics might believe it to be a vector.

      Which is not a footgun.

        It actually can be, mathematical vectors gaurantee for example that x+y == y+x for all x,y, but no such gaurantee can be ever made on the user-defined operator+, indeed you can't even gaurantee that it is defined to begin with, let alone in the manner prescribed by linear algebra.

      The language is designed to replace, by progression, C++ for C++ developers. Mathematicians are probably better suited to using R, Julia, Octave, or Wolfram.
