element-wise assignment

tmpd = Dict([1, 2, 3] .=> ["one", "two", "three"])

element-wise function call

typeof.([1, 1.0, "one"])

inline latex examples

f\_1<tab>
1 \in<tab> [1, 2, 3]

anonymous function

x->sin(x)
(x->sin(x))(\pi<tab> / 2)
# call with, e.g. rot(pi/2)([1, 0])
rot(t) = ((x,y),) -> [cos(t)*x + sin(t)*y, -sin(t)*x + cos(t)*y]
# another way, call with `rot(pi/2)([1, 0])`
rot(t) = ((x, y),) -> [cos(t) sin(t); -sin(t) cos(t)]*[x, y]

matrix product conventions

[1 2] * [1, 2]   # == 5

add a date

using Dates
datetoday = Dates.today()
datetoday + Dates.Day(35*7)   # 35 weeks
datetoday + Dates.Year(1234) + Dates.Month(3) + Dates.Day(2)
