the road ahead
SHORT TERM =============  (for curvature-based VR)

Outer products
    syntax [DONE]
    IL and codegen

Add M dot v, v dot M, and M dot N

Identity matrix [DONE up to code generation]

trace [DONE]

expand trace in mid to low translation

extend norm (|exp|) to all tensor types

extend normalize to all tensor types

Use ∇⊗ etc syntax
    syntax [DONE]
    IL and codegen

Add sequence types
	types: ty '{' INT '}'
	value construction: '{' e1 ',' … ',' en '}'
	indexing: e '{' e '}'

IL support for higher-order tensor values (matrices, etc).
    tensor construction
    tensor indexing and slicing
    verify that hessians work correctly

Add type aliases for color types
    rgb = real{3}
    rgba = real{4}

stabilize {} code block

  Infix dot product and cross product
  lerp on scalars and vectors

other SHORT TERM =============  (needed for LIC)

vector fields: convolution on vector images

MEDIUM TERM ================== (needed for streamlines & tractography)

ability to emit/track/record variables into dynamically re-sized
runtime buffer

evals & evecs for symmetric tensor[3,3]

tensor fields: convolution on general tensor images

other MEDIUM TERM ============ (needed for particles)

run-time birth and death of strands

"initially" supports lists

"initially" supports lists of positions output from 
different initalization Diderot program

spatial data structure that permits strands' queries of neighbors

LONG TERM ==================== 

co- vs contra- index distinction

some indication of tensor symmetry
(have to identify the group of index permutations that are symmetries)

dot works on all tensors

outer works on all tensors

Einstein summation notation

"tensor comprehension" (like list comprehension)
